States of Matter Questions

Multiple choice

Condensation is

  1. when water turns into a gas without boiling

  2. when a solid warms up and becomes a liquid

  3. when a gas cools and becomes a liquid

  4. when a gas cools directly into a solid
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Condensation is the phase change where a gas loses energy, cools down, and transitions into a liquid state.

Multiple choice

Sublimation changes _______ into ________.

  1. Gas into Liquid

  2. Gas into Solid

  3. Solid into Gas

  4. Solid into Liquid
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Sublimation is the process where a solid changes directly into a gas, bypassing the liquid phase.

Multiple choice

What are the three states of matter

  1. Solid, Liquid, Magma

  2. Ice, Water, Steam

  3. Solid, Liquid, Gas

  4. Solid, Slime, Magma
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The three fundamental states of matter commonly taught in introductory science are solid, liquid, and gas.

Multiple choice

Water is a solid at room temperature

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Water exists as a liquid at standard room temperature. It only becomes a solid (ice) at temperatures at or below 0 degrees Celsius.

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

A distinctive property of the liquid state is____________.

  1. compressibility

  2. rigidity

  3. condensation

  4. surface tension
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A distinctive property of the liquid state is surface tension, leading to wetting phenomena. Surface tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible. At liquid-air interfaces, surface tension results from the greater attraction of liquid molecules to each other (due to cohesion) than to the molecules in the air (due to adhesion).

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.

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

The rate of diffusion of liquids is __________.

  1. higher than gases

  2. lower than solids

  3. higher than solids

  4. equal to gases
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The rate of diffusion of liquids is higher than that of solids. This is due to the fact that in the liquid state, particles move freely and have greater space between each other as compared to particles in the solid state.

________ can usually be reduced by heating the liquid.

  1. Pressure

  2. Temprature

  3. Latent heat

  4. Viscosity
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Viscosity is a measure of how much a liquid resists flowing freely. Viscosity can usually be reduced by heating the liquid. When heated, the particles of the liquid move faster, allowing the liquid to flow more easily.

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

Volatile liquids have ___________.

  1. low viscosity

  2. high boiling point

  3. low boiling point

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

Volatile liquids have low boiling point. As a result, they evaporate very easily at room temperature. Because of their low boiling points, volatile liquids convert to the gas phase at a lower temperature and the gas molecules can diffuse faster than the molecules of a non-volatile liquid.
