Multiple choice chemistry matter in our surroundings diffusion in different states of matter properties of solids, liquid, and gas particle theory of matter

In an ionic solid, ${B}^{x-}$ ions constitute a ccp lattice, if ${A}^{y+}$ ion occupy $25$% of the tetrahedral voids, the possible ions in the solid are:

  1. ${A}^{+}$ and ${B}^{-}$
  2. ${A}^{2+}$ and ${B}^{4-}$
  3. ${A}^{2+}$ and ${B}^{-}$
  4. ${A}^{4+}$ and ${B}^{-}$

C Correct answer
Explanation

Let the number of B ions be N. The number of tetrahedral voids is 2N. A ions occupy 25% of 2N, which is 0.5N. The ratio A:B is 0.5:1, or 1:2. To maintain charge neutrality, if B is -1, A must be +2. Thus, A is +2 and B is -1.

Which of the following is not the state of matter?

  1. Solid

  2. Liquid

  3. Gas

  4. Vapour

D Correct answer
Explanation

Matter has three main state of matter that is solid, liquid and gas. Vapour is the type of substance which forms when liquid converts into the gaseous phase. It is a matter but not a state of matter.

Compressibility is minimum in case of :

  1. solid.

  2. liquid.

  3. both (a) and (b).

  4. gas.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In case of solid the inter-molecular force of attraction is very strong and inter-particle spaces are very small. So, it is very difficult to compress the solid.


Hence, the correct option is $A$.

Which of the following states of matter exerts pressure on the walls of the container?

  1. Solids

  2. Liquids

  3. Gases

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Among all the states of matter, gases exert pressure in all directions. Liquids and solids exert pressure along the gravity (generally).


Because of negligible force of attraction between particles of gas, the particles of gas have the highest kinetic energy.

Liquids and gases ....................... on heating.

  1. contract

  2. expand

  3. melt

  4. none of above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Liquids and gases expand when they are heated. This is because the particles in liquids and gases move faster when they are heated than they do when they are cold. As a result, the particles take up more volume. This is because the gap between particles widens, while the particles themselves stay the same size.

Which of the following is a type of latent heat?

  1. Latent heat of fusion

  2. Latent heat of vaporization

  3. Both a and b

  4. None of above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The latent heat is used in change of states of matter, such as from solid to liquid or from liquid to gas without rising in temperature. When solid changes into liquid, the heat required for changing the state without rise in temperature is called the Latent Heat of Fusion. When liquid changes into gas because of rise in temperature, the heat required changing the state without rising in temperature is called the Latent Heat of vaporization.
