Heat vs. Temperature

Heat is a form of energy, whereas temperature is the measurement of that energy.

Heat is a form of energy that causes things to become warmer. It can be produced through friction, combustion, electricity, and other sources. Heat flows from a higher temperature to lower temperature when two bodies are brought together. It is a form of energy measured in Joules. As energy, heat has the ability to do work.

Temperature is a measurement in degrees of the amount of heat. It can be measured in degrees Celsius, Fahrenheit, or Kelvin. Temperature is measured using a thermometer.

Heat is based on the number of atoms in a substance multiplied by the amount of energy (both kinetic and potential) they each possess, whereas temperature is based on how fast atoms are moving.
