Heat and temperature are related and often confused. More heat usually means a higher temperature.
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.
