Thermal Energy Concept Check

What is the definition of temperature?

• The amount of heat in an object

• The average kinetic energy of the particles in an object

• The amount of cold in an object

• The average potential energy of the particles in an object

Which of the following is NOT true of heat and temperature?

• Heat and temperature are the same thing

• Heat is a transfer of energy

• Heat moves from hot to cold

• Temperature represents how hot or cold an object is
