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.

WebHeat transfer can be defined as the process of transfer of heat from an object at a higher temperature to another object at a lower temperature. Therefore heat is the measure of kinetic energy possessed by the particles in a given system. When the temperature of a system increases then its kinetic energy of the particles will also increase.
