What would pressure be if volume was 0

Answers

Answer:

The lower the temperature, the lower the pressure inside of the sphere. If the exact values were plotted out, a linear relationship would be apparent. Extrapolating this line to the point where there would be no pressure yields absolute zero, which is about -273.15 degrees Celsius.

Explanation:

In this simulation, you will be exploring the relationship between temperature and pressure while keeping volume
constant. Click here to begin. Select the Explore box. Answer the questions as you perform the steps.
1. Raise and push down the pressure pump handle to add gas molecules to the container. The initial temperature is
300 K (27º) and the pressure has a range of 5.4-6.2 atm. Notice the pressure values change as the particles
collide with the wall.
2. Click on the bucket to raise the temperature of the container to approximately 400 K (127°C). What happened to
the pressure?
Approximately what pressure range did you observe?
3. Click on the bucket to reduce the temperature to approximately 200 K (-73°C). What happened to the pressure?
Approximately what pressure did you observe?
4. What gas law mathematically shows the relationships between temperature and pressure?

Answers

Answer:

increased, 7.5-8.3 atm; decreased, 3.5-4.3 atm; Gay-Lussac's Law

Explanation:

1. The collision of gas molecules, results in the pressure increases.

2. The pressure of the system with an increase in the temperature has been 7.2-8.2 atm.

3. The pressure of the system with a decrease in the temperature has been 3.6-4.1 atm.

4. The relationship between the molecules has been given by Gay-Lussac's Law.

The relationship between the temperature and pressure has been given in the gaseous molecules with the ideal gas equation.

1. The temperature has been directly proportional to the temperature. Thus, with an increase in pressure, there has been an increase in temperature and vice versa.

With the collision of the gas molecules with the wall, there has been the liberation of the energy that increases the temperature. The increase in temperature mediates the increase in pressure.

Thus, with the collision of gas molecules, the pressure increases.

2. The relationship between the pressure and temperature has been given as:

[tex]\dfrac{P1}{T1}=\dfrac{P2}{T2}[/tex]

The initial temperature [tex]T1=300\;\text K[/tex]

Final temperature [tex]T2=400\;\text K[/tex]

Initial pressure, [tex]P1=5.4-6.2\;\text {atm}[/tex]

Final pressure, [tex]P2[/tex]

Substituting the values for calculating P2 as:

[tex]\rm \dfrac{5.4-6.2\;atm}{300\;K}=\dfrac{P2}{400\;K}\\\\\textit P2 = \dfrac{5.4-6.2\;atm}{300\;K}\;\times\;400\;K\\\\\textit{P}2=7.2-8.2\;atm[/tex]

The pressure of the system with an increase in the temperature has been 7.2-8.2 atm.

3. The pressure with the reduction of temperature has been given by :

[tex]\dfrac{P1}{T1}=\dfrac{P2}{T2}[/tex]

The initial temperature [tex]T1=400\;\text K[/tex]

Final temperature [tex]T2=200\;\text K[/tex]

Initial pressure, [tex]P1=7.2-8.2\;\text {atm}[/tex]

Final pressure, [tex]P2[/tex]

Substituting the values for calculating P2 as:

[tex]\rm \dfrac{7.2-8.2\;atm}{400\;K}=\dfrac{P2}{200\;K}\\\\\textit P2 = \dfrac{7.2-8.2\;atm}{400\;K}\;\times\;200\;K\\\\\textit{P}2=3.6-4.1\;atm[/tex]

The pressure of the system with a decrease in the temperature has been 3.6-4.1 atm.

4. The relationship between the molecules has been given by Gay-Lussac's Law. The law states that pressure has been directly proportional to the absolute temperature of the system.

Why does ketchup flow faster when heated?

Answers

Answer: Explanation:

With an increase in temperature, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. The gas viscosity will increase with temperature. ... With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.

The increase in temperature causes the kinetic or thermal energy to increase and the molecules become more mobile. The attractive binding energy is reduced and therefore the viscosity is reduced.

liquids show a reduction in viscosity with increasing temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.

B) 24.2 kg Fe (NO3) 2
C) 0.5912 g C8H18
D) 104 kg CaO
Express all answers to 4 sig figs

Answers

Answer:

A = 1.627 ×10²³ molecules of CF₂Cl₂.

B = 809.4 ×10²³ molecules of Fe(NO₃)₂.

C = 0.03117 ×10²³ molecules of C₈H₁₈.

D= 1116 ×10²³ molecules of CaO.

Explanation:

A)

Given data:

Mass of CF₂Cl₂ = 32.66 g

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles = mass/ molar mass

Number of moles = 32.66 g/ 120.9 g/mol

Number of moles = 0.2701 mol

Number of molecules:

1 mole = 6.022×10²³ molecules

0.2701 mol×6.022×10²³ molecules / 1mol = 1.627 ×10²³ molecules of CF₂Cl₂.

B) Given data:

Mass of Fe(NO₃)₂ = 24.2 Kg  (24.2×1000 = 24200 g)

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles = mass/ molar mass

Number of moles = 24200 g/ 180 g/mol

Number of moles = 134.4 mol

Number of molecules:

1 mole = 6.022×10²³ molecules

134.4 mol×6.022×10²³ molecules / 1mol =809.4 ×10²³ molecules of Fe(NO₃)₂.

C) Given data:

Mass of C₈H₁₈= 0.5912 g

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles = mass/ molar mass

Number of moles = 0.5912 g/ 114.22 g/mol

Number of moles = 0.005176 mol

Number of molecules:

1 mole = 6.022×10²³ molecules

0.005176 mol×6.022×10²³ molecules / 1mol =0.03117 ×10²³ molecules of C₈H₁₈.

D) Given data:

Mass of CaO = 104 Kg  (104×1000 = 104,000 g)

Number of moles = ?

Number of molecules = ?

Solution:

Number of moles = mass/ molar mass

Number of moles = 104,000 g/ 56.1 g/mol

Number of moles = 1854 mol

Number of molecules:

1 mole = 6.022×10²³ molecules

1854 mol×6.022×10²³ molecules / 1mol = 1116 ×10²³ molecules of CaO.

When Silver (Ag) forms a metallic bond with other Silver atoms, what do the valence electrons move into? A. the all go to the same Silver atom B. the bond with the oxygen in the atomsphere C. they escape to free space D. the sea of electrons

Answers

Answer:

D. the sea of electrons

Explanation:

Metallic bonds are defined as the bonds formed between two or more metals. Silver atom form metallic bond with other silver atoms.

In metallic bond, the free electrons or valence electrons present in s and p orbitals delocalize. The valence electrons do not move around the atoms or enter the atoms whereas they form a sea of electrons in which they surround the nuclei (positively charged) of the metal ions interacting. The valence electrons are then freely move in the space between the atomic nuclei.

Hence, the correct answer is "D. the sea of electrons".

If a boulder sits at rest on top of a mountain what conclusion can be made about the forces acting on the

Answers

A boulder sits at rest on top of a mountain. What conclusion can be made about the forces acting on the boulder? The forces acting on the boulder are balanced (net force equals zero).

If a boulder sits at rest on the top of the mountain , the forces acting on the boulder are zero as it is in the state of rest.

What is a force?

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.
