What is the relationship between heat and thermal energy?
Heat is a form of energy that is transferred from one object to another due to a difference in temperature. It is a measure of the total kinetic energy of the particles in an object.
Thermal energy is the internal energy of a system due to the movement of its particles. It is a form of energy that is directly related to the temperature of a substance.
Heat and thermal energy are closely related, as heat is the transfer of thermal energy from a warmer object to a cooler object. The amount of heat transferred is directly proportional to the change in thermal energy of the system.
Heat is measured in units of energy, such as joules or calories. The amount of heat transferred can be measured using a calorimeter, which measures the temperature change of a substance when heat is added or removed.
The relationship between heat and thermal energy is affected by the temperature difference between objects, the specific heat capacity of the materials, the amount of mass, and the duration of heat transfer. It is also affected by external factors such as insulation and heat loss to the surroundings.
