What is Heat and Temperature?

Heat is a form of energy that moves from one object to another due to a difference in temperature. It naturally transfers from a warmer object to a cooler one until both reach the same temperature, a state known as thermal equilibrium. In the International System of Units (SI), heat is measured in joules (J), though it can also be expressed in calories or British thermal units (BTUs). Temperature measures the average kinetic energy of the particles in a substance, indicating how hot or cold something is compared to a standard scale. Unlike heat, which involves energy transfer, temperature is a scalar quantity that represents the thermal state of a material. Enroll now at Tutoroot.
