What intermolecular force is present for ne to form a liquid at low temperatures?.

Answers

Answer 1

For ne to form a liquid at low temperatures, an intermolecular force known as London dispersion forces must be present.

What are intermolecular forces ?

Different sections of a molecule may have a positive or negative charge, which can lead them to arrange into particular forms in a solid. These intermolecular forces are what draw molecules together. The melting and boiling points of a substance depend on the strength of intermolecular forces.

Neon is a noble gas, an inert gas. The London dispersion force exists between them as an intermolecular force. Think of two Ne atoms that are close to one another. Due to their rapid speed, electrons eventually become asymmetrical in their distribution. London dispersion forces, which are transient dipoles caused by unequal electron distributions, are the only intermolecular forces it is capable of showing. The ensuing London dispersion forces can provide weak attractions between neon atoms because neon has electrons. Neon is a monatomic gas that exists. In other words, each neon atom is self-contained and does not interact chemically with any other atoms. As a result, neon's electron distribution can be said to be symmetrically undisturbed, making it nonpolar.

If the slit width was less than the wavelength of light being used for the first part of the experiment, then you would expect to see only a single order of minima.

What is minima?
The largest and lowest value of a function, either within a specific range (the neighbourhood or relative extrema) or on the entire domain, are collectively referred to as extrema (plural of extremum) in mathematical analysis (the global or absolute extrema). One of the earliest mathematicians to suggest the general method of adequacy for determining the minima and maxima of functions was Pierre de Fermat.

The minimum and maximum of a set are the greatest as well as least elements in the set, as defined by set theory. There are no minimum or maximum values in unbounded infinite sets, like the set of real numbers.

This is because when the slit width is less than the wavelength of light, the diffraction pattern is dominated by the single slit and the interference of light waves is insignificant, resulting in a single order of minima.

if properties are allowed to change within the control volume, the processes are called flow. (textbook chapter 5)

Answers

Transient-flow are processes that involve changes within a control volume with time.

Explain  transient flow and its effects?

Unsteady flow is a flow in which velocity and pressure vary with time. A transient flow condition is when a change occurs in the fluid system, such as starting or stopping a pump, opening or closing a valve, or changing the tank level. Otherwise, the system is in steady state. In many cases, transient flow conditions exist as oscillating pressure and velocity waves for some time after the original event that caused them.

Transient flow is commonly referred to as surge or water hammer, and the terms are often interchanged. Strictly speaking, however, surge is when the fluid's mass vibration is the dominant force and the fluid's compressibility is not important. For example, two connected reservoirs vibrate up and down. Water hammer on the other hand is where the compressibility of the fluid has the dominant effect such as the sudden closure of a valve. Transient flow can result in significant transient pressures that may exceed the design limit of the pipes and fittings. Or it may be important to maintain a steady flow for example in the process industry. Therefore a detailed understanding of transient flow can be very important.

Thus, Transient-flow are processes that involve changes within a control volume with time.

If a spinning star gets larger in diameter its rotation rate is decreases.

As the radius of a spinning star decreases, some of its rotational inertia is lost, which results in a rise in rotational speed owing to the conservation of angular momentum. Because stars gradually slow down over time, much like a top spinning on a table, a star's spin rate depends on its age.

A 1,800 kg car is parked on a road that has an elevation angle of 7°. Suppose the coefficient of static friction of the kinds of rubber and asphalt involved is 0.65.The force of static friction between the tires and the road is 2149.8 N

To find the force, the given data can be,

m = mass of the car = 1800 kg

g = acceleration due to gravity

  = 9.8 m/s²

Fg = force of gravity on the car

What is static friction?

When an object is static these irregularities get more time to be interlocked as compared to when an object is in motion thus the coefficient of static friction is more than the coefficient of sliding friction.

Force of gravity on the car is given as

Fg= mg

Substituting the values,

Fg= (1800) (9.8)

   = 17640 N

Fs= static frictional force acting on the car

From the force diagram of the car, the static frictional force is opposite to the parallel component of force of gravity on the car . hence static frictional force must balance the component of force of gravity parallel to inclined surface.

Fs =  Sin7°

As a vector quantity, a force is one that has both direction and magnitude. It is expressed as a newton in the SI system (N). F is a symbol that stands for force (formerly P).

The net force acting on an object seems to be equal to the rate that its momentum changes over time, according to the original formulation of Newton's second law.

This is because the force between two charges is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them.

the masses of the javelin, discus, and shot are 0.80 kg, 2.0 kg, and 7.2 kg, respectively, and record throws in the corresponding track events are about 98 m, 74 m, and 23 m, respectively. neglecting air resistance, (a) calculate the minimum initial kinetic energies that would produce these throws, and (b) estimate the average force exerted on each object during the throw, assuming the force acts over a distance of 2.0 m. (c) do your results suggest that air resistance is an important factor? [hint: think about if the same muscle power used in a shot throw would produce the same range for a javelin when air resistance is neglected.]

Answers

Let us assume θ = 45⁰, so sin(2θ) = 1

R = v² x sin(2θ) / g = v² / g

v² = R x g

a) To find the kinetic energy,

E = 0.5 x mv² = 0.5 x R x g

E(javelin) = 0.5 x 0.8 x 9.8 = 384 J

E(discuss) = 0.5 x 2 x 74 x 9.8 = 725.2 J

E(shot) = 0.5 x 7.2 x 23 x 9.8 = 811.4 J

b) To find the average force exerted,

F = W / Δx = Δk / Δx

F(javelin) = 384 / 2 = 192 N

F(discuss) = 725.2 / 2 = 363 N

F(shot) = 811.4 / 2 = 406 N

c) Yes, air resistance is an important factor.

Therefore, air resistance must affect each of them very differently because the average force the person could throw with, should be same.

FOR CHEMISTRY:

A small package of Reese's Pieces candy contains 234 calories and 12 grams of fat. Assuming the package contains 36 pieces, what is the maximum number of pieces I could eat without exceeding 150 calories?

Answers

The maximum number of 23 pieces a person could eat without exceeding 150 calories.

What are calories?

A calorie can be described as unit of energy. The large calorie, food calorie was originally described as the amount of heat required to raise the temperature of 1 Kg of water by one degree Celsius.

The small calorie was defined as the amount of heat required to cause the same increase in one gram of water.  In physics and chemistry, the calorie usually refers to a small unit of energy. One calorie is equal to exactly 4.184 Joules.

Given, the  234 calories contained in pieces of candy = 36

Then 150 calories contain by pieces of candy = (36/234) ×150 = 23

Therefore, a maximum number of 23 pieces someone could eat without exceeding 150 calories.

If the expansion of the Universe is currently accelerating, can we conclude that the Universe will necessarily expand forever? Why?

Answers

The universe will expand forever.

Why is it said the universe will expand forever?

Cosmologists generally agree that the universe has a "flat" shape (i.e., parallel lines remain parallel) and will expand indefinitely. If the mean density falls below the critical density, there won't be enough matter in the universe to stop the expansion; the cosmos will continue to grow indefinitely. The galaxies will eventually grow progressively further apart. Everything in the universe is included, from the tiniest molecule to the greatest galaxy. The cosmos has been growing since the Big Bang approximately 13.7 billion years ago, and its size may be unlimited.
