distinguish between heat and temperature
Answers
♠HEllo!! ♠
Heat and temperature are related to each other, but are different concepts. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. ... Temperature does not depend on the size or type of object.

Answer:
Heat (symbol: Q) is energy. It is the total amount of energy (both kinetic and potential) possessed by the molecules in a piece of matter. Heat is measured in Joules.
Temperature (symbol: T) is not energy. It relates to the average (kinetic) energy of microscopic motions of a single particle in the system per degree of freedom. It is measured in Kelvin (K), Celsius (C) or Fahrenheit (F).
When you heat a substance, either of two things can happen: the temperature of the substance can rise or the state of substance can change.

Heat Temperature
Definition Heat is energy that is transferred from one body to another as the result of a difference in temperature. Temperature is a measure of hotness or coldness expressed in terms of any of several arbitrary scales like Celsius and Fahrenheit.
Unit Joules Kelvin, Celsius or Fahrenheit
Symbol Q T
SI unit Joule Kelvin
Particles Heat is a measure of how many atoms there are in a substance multiplied by how much energy each atom possesses. 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.
Ability to do work Heat has the ability to do work. Temperature can only be used to measure the degree of heat.
