Which of the following objects has the most thermal energy?

• A pot of tea heated to 75°C

• A pot of tea heated to 60°C

• A pot of tea heated to 55°C

• A pot of tea heated to 45°C

A 200 mL glass of juice at room temperature has more thermal energy than a 100 mL glass of the same juice at room temperature. This is an example of how thermal energy is affected by the object's

• environment

• sample size

• mass

• state

In which of these places do the particles in the air have the greatest average energy of motion?

• outside on a winter day

• inside an air conditioned building

• inside a freezer

• outside on a summer day

Which of the following forms of electromagnetic energy that travel to Earth is felt as heat?

• visible light

• radio waves

• gamma rays

• infrared waves

Your family is toasting marshmallows over a camp fire. This is an example of which type of heat transfer?

• conduction

• convection

• radiation

• convection current

Heat is the movement of thermal energy from a warmer substance to a cooler substance. Which of the following would be the best hypothesis to investigate heat transfer?

• If heat is transferred, one material will decrease in temperature, and another material will increase in temperature.

• Temperature measures the average kinetic energy of the particles in a material, so you need to record the temperature of all materials you study.

• Heat can be transferred by the movements of currents in a fluid, such as water boiling in a pot.

• If heat is transferred, good conductors such as metals or floor tiles must be involved, and they will show a change of temperature.

Use the diagram to answer: What process causes particles in State A to change to State B?

• condensation

• evaporation

• freezing

• melting

Which of the following is an example of an endothermic change?

• an ice cube melts

• a car burns fuel

• a lantern provides light

• a radiator heats a home

What must happen in order for water to change state?

• It must maintain its thermal energy level.

• It must absorb or release energy.

• It must be insulated.

• It must convert thermal energy to solar energy.

Which of the following statements about chemical energy is true?

• Chemical energy is the energy stored in the chemical bonds between atoms.

• Chemical energy is not stored in food.

• Other forms of energy never change into chemical energy.

• Chemical energy cannot change into other forms of energy.
