What to Focus On

  • Heat is a form of energy.
  • Heat flows from hot body to cold body.
  • SI unit of heat is joule.
  • Temperature tells hotness or coldness.
  • Temperature decides direction of heat flow.
  • SI unit of temperature is kelvin.
  • Heat is energy.
  • Temperature is a measure of hotness or coldness.
  • Heat depends on mass and material.

Common Mistakes to Avoid

Heat and temperature are the same thing.

Heat always flows from a body with more heat to a body with less heat.

1 joule is equal to 1 calorie.

Memory Tips

Heat as internal energy that flows from hot body to cold body

Temperature as the measure that tells thermal state and direction of heat flow

Difference between heat and temperature
