An increase in volume due to heating is called:
An increase in volume due to heating is called:
The answer is thermal expansion. Thermal expansion happens when substances are heated and the particles speed up and take up more space.
The answer is thermal expansion. Thermal expansion happens when substances are heated and the particles speed up and take up more space.
Compare your answer with the correct one above
Cooling causes particles in substances to:
Cooling causes particles in substances to:
The answer is "slow down." When a substance cools it loses its thermal energy which causes the particles to slow down.
The answer is "slow down." When a substance cools it loses its thermal energy which causes the particles to slow down.

The particles in the image on the far left most likely:
The particles in the image on the far left most likely:
The answer is "belong to a solid and are vibrating in place." The image shows that the particles are 'stuck together' in a solid configuration. These particles do have kinetic energy so they are vibrating and not completely lacking movement.

Removing thermal energy from a substance will:
Removing thermal energy from a substance will:
The answer is all of the these because removing thermal energy will change a substance's state, temperature, and particle motion.
The answer is all of the these because removing thermal energy will change a substance's state, temperature, and particle motion.

The image shows the particles of a substance in its three states. The kinetic energy of the particles increases as:
The image shows the particles of a substance in its three states. The kinetic energy of the particles increases as:
The answer is "both as it changes from a solid to a liquid and when it changes from a liquid to a gas." As the temperature of a substance increases, so does the kinetic energy of particles increases.
The answer is "both as it changes from a solid to a liquid and when it changes from a liquid to a gas." As the temperature of a substance increases, so does the kinetic energy of particles increases.

In order to change a substance from a solid to a liquid, you would have to:
In order to change a substance from a solid to a liquid, you would have to:
The answer is "add thermal energy" because the state change from a solid to a liquid requires heat.

The constant motion of particles in substances gives them their kinetic energy. We measure this kinetic energy as:
The constant motion of particles in substances gives them their kinetic energy. We measure this kinetic energy as:
The answer is "temperature." Temperature is by definition, the measure of the kinetic energy of a substance.
