Temperature and Heat Quiz

What physical quantity expresses the degree of hotness or coldness of a substance and is directly related to the average kinetic energy of its constituent particles?

• Heat

• Temperature

• Thermal Energy

• Specific Heat

Which statement accurately describes the fundamental distinction between heat and temperature?

• Heat is the average kinetic energy of particles, while temperature is the total energy transferred.

• Heat is the total energy transferred due to a temperature difference, while temperature is the average kinetic energy of particles.

• Heat and temperature are interchangeable terms for the same physical phenomenon.

• Heat is measured in degrees Celsius, and temperature is measured in Joules.
