Answer:
The difference between solid, liquid and gas can be drawn clearly on the following grounds:
A substance having structural rigidity and has a firm shape which cannot be changed easily is called solid. A water-like fluid, that flows freely, having a definite volume but no permanent shape, is called liquid. Gas refers to a state of matter, do not have any shape but conform to the shape of the container, completely, in which it is put in. While solids have certain shape and volume, liquids only have definite volume but not shape, gases neither have shape nor volume. The level of energy is highest in gases, medium in liquid and lowest in solids. The compression of solids is difficult, liquids are nearly incompressible, but gases can be easily compressed. Molecular arrangement of solids is regular and close, but liquids have irregular and sparse molecular arrangement and gases, too have random and more sparse arrangement of molecules. The molecular arrangement in solids is well organised. However, the layers of molecules slip and slide over one another, in the case of liquids. In contrast, the particles in gases are not at all organised, due to which the particles move randomly. When it comes to fluidity, solids cannot flow, however, liquids can flow and that also from the higher level to lower level. As against this gases flows in all directions. The spaces between the molecules and the kinetic energy are minimum in solids, medium in liquid and maximum in gases. So, the motion of molecules is negligible in solids, whereas in liquids, the erratic, random motion of molecules can be seen. Unlike gases, which have the free, constant and random motion of molecules. In solids, the particles are held tightly by strong intermolecular attraction, although in liquids the attraction between particles is intermediate. As against this, the particles are loosely held, because the intermolecular attraction is weak. The speed of sound is highest in solids, while the speed is a bit slower in liquids and minimum in gases. As solid have a definite shape and size, they do not require a container for storage. Liquids cannot be stored without a container. Conversely, for storing gases, a closed container is required.
Explanation:
Definition of Solid
By the term ‘solid’ we mean the type of matter which is rigid in structure and opposes the change in its shape and volume. The particles of a solid are tightly bound and well-arranged in a regular pattern, which does not allow the particles to move freely from one place to another. The particles continuously vibrate and twist, but there is no motion, as they are too close to each other. As the intermolecular attraction is maximum in solids, and because their shape is fixed, and the particles stay, where they are set. In addition to this, the compression of solid is very tough, as the spaces between molecules are already very less.
Definition of Liquid
A free flowing substance of constant volume having consistency is called as the liquid. It is a type of matter which do not have its shape but takes the shape of the vessel, in which it is held. It contains small particles, which are held tightly by intermolecular bonds. One of the unique property of liquid is surface tension, a phenomenon which makes the fluid possess the minimum surface area. The compression of liquid is a nearly difficult, due to less gap between particles. The particles are closely bound, but not as tightly as in the case of solid. Thus allowing the particles to move around and mix with one another.
Definition of Gas
Gas is described as a state of matter which diffuses freely in all directions and fills the entire space available, regardless of the quantity. It is made up of particle that does not have a certain shape and volume. The particles can be individual atoms or elemental molecules or compound molecules. In gases, the molecules are loosely held, and so there is a lot of space between molecules to move freely and constantly. Due to this characteristic, the gas has the ability to fill any container, as well as it can be easily compressed.

which particle has the least mass
a. electron
b. proton
c. neutron
d. all have the same mass
Answer:
b. proton
Explanation:
The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1.
What is the molality of a solution containing 30.0 g of napthalalene (C10H8) dissolved in 500.0 g of toulene? Please provide work. Thanks in advance!
Answer:
0.468 m
Explanation:
From the question given above, the following data were obtained:
Mass of napthalalene (C₁₀H₈) = 30 g
Mass of toulene = 500 g
Molality =?
Next, we shall determine the number of mole in 30 g of C₁₀H₈. This can be obtained as follow:
Mass of C₁₀H₈ = 30 g
Molar mass of C₁₀H₈ = (12×10) + (8×1)
= 120 + 8
= 128 g/mol
Mole of C₁₀H₈ =?
Mole = mass / molar mass
Mole of C₁₀H₈ = 30 / 128
Mole of C₁₀H₈ = 0.234 mole
Next, we shall convert 500.0 g of toulene to Kg. This can be obtained as follow:
1000 g = 1 Kg
Therefore,
500 g = 500 g × 1 Kg / 1000 g
500 g = 0.5 Kg
Finally, we shall determine the molality of the solution. This can be obtained as follow:
Mole of solute (C₁₀H₈) = 0.234 mole
Mass of solvent (toulene) = 0.5 Kg
Molality =?
Molality = mole of solute / Kg of solvent
Molality = 0.234 / 0.5
Molality = 0.468 m

24 grams of CH4 was added to the above reaction. Calculate the theoretical yield of CO2. A. 66 grams B. 33 grams c. 132 grams. D 8.72 grams
Answer:
Option A. 66 g
Explanation:
We'll begin by writing the balanced equation for the reaction. This is given below:
CH₄ + 2O₂ —> CO₂ + 2H₂O
Next, we shall determine the mass of CH₄ that reacted and the mass of CO₂ produced from the balanced equation. This is illustrated below:
Molar mass of CH₄ = 12 + (4×1)
= 12 + 4 = 16 g/mol
Mass of CH₄ from the balanced equation = 1 × 16 = 16 g
Molar mass of CO₂ = 12 + (16×2)
= 12 + 32 = 44 g/mol
Mass of CO₂ from the balanced equation = 1 × 44 = 44 g
SUMMARY:
From the balanced equation above,
16 g of CH₄ reacted to produce 44 g of CO₂.
Finally, we shall determine the theoretical yield of CO₂. this can be obtained as follow:
From the balanced equation above,
16 g of CH₄ reacted to produce 44 g of CO₂.
Therefore, 24 g of CH₄ will react to produce = (24 × 44) /16 = 66 g of CO₂.
Thus, the theoretical yield of CO₂ 66 g
The theoretical yield of CO₂ is 66 grams.
The balanced chemical equation of the reaction is as follows:
CH₄ + 2O₂ → CO₂ + 2H₂O
mass number of CH₄ = 16 g
mass number of CO₂ = 44 g
Therefore,
16 of CH₄ produced 44g of CO₂
24 g of CH₄ will give ? of CO₂
cross multiply
mass of CO₂ produced = 24 × 44 / 16
mass of CO₂ produced = 1056 / 16
mass of CO₂ produced = 66 grams

Answer:
The appropriate alternative is option C "[tex]5.09\times 10^{14} \ s[/tex]".
Explanation:
The given value is:
Energy of photon,
E = [tex]3.37\times 10^{-19} \ J[/tex]
As we know,
h = [tex]6.626\times 10^{-34} \ Js[/tex]
Now,
The frequency of the light will be:
⇒ [tex]E=hv[/tex]
On substituting the given values, we get
⇒ [tex]3.37\times 10^{-19}=6.626\times 10^{-34}\times v[/tex]
On solving, we get
⇒ [tex]v=5.09\times 10^{14} \ s[/tex]
If the energy of a photon of light is 3.37 x 10⁻¹⁹ J, then the frequency of the light is 5.09 x 10¹⁴ per sec.
How we calculate frequency?Frequency of light will be calculated by using the below formula:
E = hυ, where
E = energy of photon = 3.37 x 10⁻¹⁹ J
h = plank's constant = 6.626 × 10⁻³⁴ Js
Putting these values on the above equation and calculate for the frequency as:
υ = 3.37 x 10⁻¹⁹ J / 6.626 × 10⁻³⁴ Js = 5.09 x 10¹⁴ per sec
Hence, option (C) is correct i.e. 5.09 x 10¹⁴ per sec.

Answer:
why does the temperature change?
Daily air temperatures at Earth's surface are controlled by the incoming and outgoing energy. During the day, the air temperature increases as energy gains exceed the energy lost from Earth's surface. Throughout the night, the air temperature decreases as Earth's surface loses more energy than it receives.
What are examples of natural products?
Classes. The broadest definition of natural product is anything that is produced by life, and includes the likes of biotic materials (e.g. wood, silk), bio-based materials (e.g. bioplastics, cornstarch), bodily fluids (e.g. milk, plant exudates), and other natural materials (e.g. soil, coal).
