Imagine the temperature increases (gets hotter), turning a liquid into a gas. What happens to the kinetic energy of the liquid if temperature increases?

• kinetic energy increases and molecules move more

• kinetic energy decreases and molecules move less

What happens to the heat if thermal energy is added to the liquid?

• Heat increases (goes up)

• Heat decreases (goes down)

If the liquid is heated to a gas and has higher thermal and kinetic energy, what happens to the movement of the molecules?

• the molecules move slower and spread out

• the molecules move faster and spread out

• the molecules move slower and get close together

• the molecules move faster and get close together

True or False. Popcorn pops because it is heated, causing thermal energy, kinetic energy and temperature to increase the movement of molecules and the pressure on the popcorn kernel.

• True

• False

In step 5, kinetic (moving) energy and thermal energy (heat) of the particles decreases, causing the particles to move less and the state of matter to change back to a solid

• True

• False

Take notes on your vocabulary and chart.

Kinetic energy = motion of particles

Thermal energy = heat

State of Matter = solid, liquid, gas

increase = goes up

decreases = goes down

• I took notes.

• I didn't take notes.
