1. Difference Between Heat and Temperature

Heat: Heat is the transfer of thermal energy from one body to another due to a temperature difference. It depends on the system's mass, specific heat, and temperature change. Measured in joules (J).

Temperature: Temperature is the measure of the average kinetic energy of the particles in a substance. It tells us how hot or cold something is. Measured in degrees Celsius (°C), Kelvin (K), etc.
