Question

What is the difference between heat and temperature?

Answer 1

Heat is energy that is transferred from one body to another as the result of a difference in temperature. Heat is a measure of how many atoms there are in a substance multiplied by how much energy each atom possesses. The SI unit of heat is Joules. Temperature is a measure of hotness or coldness expressed in terms of any of several arbitrary scales like Celsius and Fahrenheit. Temperature is related to how fast the atoms within a substance are moving. The ‘temperature’ of an object is like the water level – it determines the direction in which ‘heat’ will flow. The SI unit of temperature is Kelvin, Celsius or Fahrenheit.
