# Difference between Heat and Temperature

## Heat vs. Temperature

What is Difference between Heat and Temperature? It is no longer strange that in our day to day we meet with people (or even ourselves) who confuse different concepts by believing that they refer to the same thing. Among the terms that generate more confusion in people, there are those that have to do with science; but above all with physics.

## Difference between Heat and Temperature

Now, we will see what the differences between heat and temperature are. Heat and temperature are related to each other, but to understand this association one must be familiar with the concept of kinetic energy of objects.

The kinetic energy was first discovered by the Earl of Rumford, who noticed that heat was produced in the barrel hole of a barrel. He deduced that this was due to the movement that took place in the object. From all this he also deduced that every time a force acts on a body and causes it to move, it is working with energy: kinetic energy. This is his most important contribution to thermodynamics. The importance of knowing this concept is due to the fact that the heat is comprised between the kinetic energy.

Temperature

The temperature is basically the measurement of the average kinetic energy of the molecules. This means that the temperature of something will be lower if the average kinetic energy of the molecules is low; while it will be high if the kinetic energy is high.

Temperature refers to the extent of what is hot, cold or warm with respect to some standard. For this purpose the thermometer is often used. Mostly the temperature is measured in degrees Celsius, but internationally, the Kelvin scale or absolute scale (Kelvin (K)) and the Fahrenheit scale are also used.

Heat

It is the energy that is transferred between the bodies or objects due to the variation of the temperature (it is important to clarify that the bodies have no heat, but thermal energy). Heat is related to temperature because it always flows from the hottest objects to the coldest objects and the temperature is the magnitude at which this flow or energy is measured.

The difference between heat and temperature is also given because in the case of temperature, it depends on the mass of the substance. For example: 30 grams of water at 70 degrees centigrade will have more thermal energy than 25 grams of water at 70 degrees centigrade. Heat can be described as the amount of thermal energy contained in an object. Heat measurement is done in Joule or July (J).

Heat can be transferred from one object to another by three different means: conduction, radiation and convection. The difference between heat and temperature is clear; since the heat is the energy and the temperature is the magnitude that is in charge of measuring that energy. To conclude, the object with the highest temperature tends to be the one that transfers the heat to the other object with the lowest temperature; the latter is that he receives the transfer.

### Key differences between heat and temperature

• The temperature is responsible for measuring kinetic energy (in this case thermal energy), while heat is the thermal energy of a body.
• The temperature is measured in degrees Celsius, Kelvin scale, or degrees Fahrenheit; while the heat is measured in Joules or Joules.
