If an object's temperature is increased, what will happen to the object's thermal energy?

• The thermal energy will not change

• The thermal energy will increase

• The thermal energy will decrease

• The thermal energy will be destroyed

What will happen to molecules as their temperature is decreased?

• The molecules' speed will increase

• The molecules spread further apart

• The molecules moved in a different pattern

When you add ice cubes to a room temperature soda in a cup, how does the thermal energy change?

• the soda absorbs cold energy from the ice cubes

• the ice cubes absorb thermal energy from the soda

• the ice cubes will give off thermal energy to the cup

• the thermal energy will increase above room temperature

Which specific heat value would indicate a material that would heat up the fastest?

• 0.48

• 0.93

• 1.60

• 3.20

You mix 100ml of ice at 32º F with 100ml of soda at 72ºF. What will be the result?

• The ice and soda will mix and reach a temperature between 32 and 72F

• The ice and soda will separate because they are different temperatures

• The ice will transfer cold energy to the soda causing the soda to freeze

• The temperature of the soda will increase above 72F and evaporate

Why does the image of the duck appear to be cut in half?

• The light does not change speed through the glass or water

• The light slows down when it goes through the glass and water

• The light is absorbed when it goes through the glass and water

• The light speeds up as it goes through the glass and water
