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

Liquids are usually difficult to_____________.

  1. hold in a container

  2. compress

  3. change state

  4. apply pressure
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Liquids are found between the solid and gas states. A trait of liquids is that they are difficult to compress.


 When you compress something, you take a certain amount of material and force it into a smaller space or volume. You force the atoms closer together.

 Liquids tend to be difficult to compress because the molecules are already close together.

Liquid and solid are both termed as ________ , while liquid and gases are termed as ___________ .

  1. condensed, fluids

  2. fluids, condensed

  3. condensed, gaseous liquid

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

The density of a liquid is usually close to that of a solid, and much higher than in a gas. Therefore, liquid and solid are both termed condensed matter. On the other hand, as liquids and gases share the ability to flow, they are both called fluids.

Which of the following statements is incorrect?

  1. Solids generally do not show diffusion

  2. Solids have negligible kinetic energy

  3. Solids cannot be compressed

  4. Solids have indefinite volume
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Any matter that is a solid has a definite shape and a definite volume. The molecules in a solid are in fixed positions and are close together. Although the molecules can still vibrate, they cannot move from one part of the solid to another part. As a result, a solid does not easily change its shape or its volume.

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 ${B}^{-}$
Reveal answer Fill a bubble to check yourself
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
Reveal answer Fill a bubble to check yourself
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.
