What happens to to the molecules in the water when water is put in an ice tray and placed into the freezer?

• the molecules will lose mass

• the molecules will gain mass

• the molecules move slower

• the molecules move faster

If you increase an objects temperature, what will happen to the object's thermal energy and why?

• It will decrease because increasing an objects temperature decreases its thermal energy

• It will increase because increasing an object's temperature increases its thermal energy

• It won't change because an object's thermal energy does not depend on its temperature

• It won't change because objects do not have any thermal energy

When would water most likely change into a gas faster?

• 32 degrees

• 55 degrees

• 80 degrees

• 100 degrees
