You're conducting a science experiment on the energy that's transferred between objects of different temperatures. What exactly are you measuring in this experiment?

• Heat

• Kinetic energy

• Radiation

• Temperature

True or False: The greater the difference in temperature of two objects, the quicker energy is transferred between them.

• True

• False

How is energy transferred? Select all that apply.

• Radiation

• Convection
