Difference between Heat and Temperature

What is HEAT?

Heat is a form of energy that is transferred through thermal conduction, convection, or radiation.

The most common type of heat transfer is the transfer of thermal energy from one object to another. This can be accomplished by direct contacts, such as when you touch something hot, or by indirect contacts, such as when air heats up and expands and then moves over your skin.

What is Temperature?

Temperature is a measure of the amount of thermal energy per unit area that a body or substance gives off or absorbs. The SI unit for temperature is the kelvin (K).

An example would be:

The temperature of a cup of coffee at room temperature (or ambient temperature) is around 200 degrees Celsius.

Difference between Heat and Temperature

The Major Difference between Heat and Temperature are explained as follows:

Temperature is the measure of what's hot or cold, while heat is related to energy.

In all cases, there's a direct correlation between the two variables, but it's an indirect correlation because "temperature" can be felt without any transfer of "heat".

The difference between heat and temperature is that heat is a measurement of energy that is transferred from one point to another, whereas temperature measures the degree of hotness at a given location.

Heat is a form of energy while the temperature is defined as the measure of the average kinetic energy in small groups of atoms. Heat is transferred from one body to another by conduction, convection, and radiation. Objects with different temperatures transfer heat between them spontaneously when they are touched or come into contact with each other.

Temperature results from the transfer of thermal energy from particles to other particles, transferring kinetic energy as well as potential energy.

Heat can exist at a higher temperature than what comes from its surroundings because it carries more inherent potential or kinetic energy - it’s hotter. You can measure this by looking at the light spectrum coming off objects you touch.

Every system or body that has absolute temperature above 0 K inherently contains certain amount of thermal energy owing to incessant random motion of its molecules. By definition, “heat” is that part of the thermal energy which can be transferred from one body to another owing to their temperature difference only. Thermal energy from a body can be transferred to other body in two basic ways, either through heat transfer or through work transfer. Out of these two ways, heat transfer spontaneously occurs only because of temperature difference. Accordingly, “temperature” is one property of the thermodynamic system by virtue of which heat can be transferred. Temperature cannot be directly transferred. It is only heat that can be transferred. This heat transfer can, however, alter temperature of a system or body.
