What is the difference between heat and temperature?

• Temperature measures the motion of molecules, and heat is the energy of motion.

• Temperature measures the motion of molecules, and heat is the energy of that motion.

• Heat is measured in calories, and temperatures is measured in joules.

• Heat is caused by the sun, and temperature is caused by conditions in the atmosphere.
