Reggie puts a beaker of ice and water on a hot plate, as shown, and turns the hot plate on.What type of change would you expect the ice to undergo?

• a purely physical change because it will change state

• a physical and chemical change because it will change state

• a purely physical change because it will form a new substance

• . a physical and chemical change because it will form a new substance

When thermal energy is removed from a substance, the substance may condense or freeze. But when something loses energy, that energy is not “lost.” The energy is transferred to something else. When the lava cools, where is the the thermal energy transferred? Select all that apply.

• Some thermal energy is transferred from the lava to the air.

• B. Some thermal energy is transferred from the lava to the ground.

• C. Some thermal energy is transferred from the lava to the water.

• D. Some thermal energy is transferred to the new solid rock that forms.

Sweating is one way the body cools itself. Which statement best explains this cooling process?

• Water condenses on the skin, adding thermal energy to the body.

• Water from the body evaporates from the skin, removing thermal energy from the body.

Clouds and fog form under similar conditions. Air pressure at higher altitudes affects the formation of clouds. As air rises, the reduced pressure allows the air to expand and cool until water vapor

 

changes into water droplets that form the clouds. What is the process which facilitates this change?

• evaporation

• condensation

• freezing

• melting

• A. Particles are gaining energy.

• B. Particle motion is decreasing.

• C. Particle motion is increasing.
