Final answer:
Temperature is the measure of the average kinetic energy of particles in a substance. Heat is the transfer of thermal energy between objects. They are related but different in their definitions.
Step-by-step explanation:
Temperature is the measure of the average kinetic energy of particles in a substance, which determines how hot or cold an object feels. It is usually measured using a thermometer and is expressed in degrees Celsius or Fahrenheit. Heat is the transfer of thermal energy between objects that are at different temperatures. It flows from an object with higher temperature to an object with lower temperature. While temperature and heat are related, they are different in that temperature is a measure of the average kinetic energy of particles, while heat is the transfer of thermal energy.
