Difference between Heat and Temperature in tabular form

The concepts of heat and temperature are closely related, since heat is a living being’s perception of an elevated temperature, while the temperature is a physical quantity that reflects the amount of heat. Heat is all the energy produced by the movement of molecules in a certain substance, while the temperature is a measure of the average molecular energy.

Heat depends on the speed at which the particles move. The quantity, size, and the number of particles also influence it. Temperature does not depend on these variables.

The heat increases or decreases the temperature. By adding heat, the temperature increases; by removing heat, it decreases. Heat is energy, while the temperature is a measure of it.

Heat Vs Temperature

Let’s go to an example:

The temperature of the coffee in a cup can be the same as the temperature of the coffee in a 5-liter jug; however, in the jar there will be more heat, because having more liquid, there will be more total thermal energy.

Measurement units

Heat: Heat enters a body in the process known as heating, and the unit of measurement that refers to the amount of thermal energy needed for the transfer is called calories and represents an energy quantity. Matter necessarily has the property of heat, since it has to do with the movement of the particles inside it.

So the unit of measurement for heat represents the amount of energy needed to transfer from one unit to another, and it is the calorie, or Joules: one calorie represents 4,184 Joules.

Temperature: Temperature is represented by more frequent units of measurement, which also quantify the activity of molecules inside matter. Temperature indicators give rise to different particularities of matter, such as state, solubility, and volume.

Regarding the state, we can affirm that there is a certain level of temperature (different depending on the substance), that once exceeded, the body stops being solid and becomes liquid, and another temperature level that once exceeded, leaves from being liquid and becomes gaseous.

The most frequent units of temperature measurement are:

• Celsius: Consider 0 degrees the level where the water goes from solid to liquid, and 100 at the level where it goes from liquid to gas,
• Fahrenheit: Where the temperature responds to a combination of substances that make 0 and 100,
• Kelvin: It is the unit of absolute temperature, zero Kelvin is the point where the substances make the least possible movement.

Body temperature

The temperature is a very important element for the body, as the vital mechanism of homeostasis that people have is what leads to the maintenance of relative constancy in terms of temperature. Very sudden oscillations in body temperature can lead to very serious problems and even death.

The normal body temperature that is generally accepted is 37 ° C, but with a certain amplitude between 36.1 ° C and 37.2 ° C. Above that temperature, the person will be said to have a low-grade fever or fever.

Examples of Temperature and Heat

Here are some examples of heat and temperature in different circumstances:

1. The heat emission produced by a focus.
2. The process of heating a liquid, whereby the hot part moves up and the cold part moves down.
3. The separation of the contained molecules to a unit of mass, and then the change from the liquid phase to the vapor when it exceeded the heat of vaporization.
4. The waters of the sea surface, which receive radiation from the sun.
5. Touching a spoon that was in a glass of very hot milk, and that consequently will also be hot.
6. The heat received by a person who is cooking, even though he is not actually in the place where the heat is produced
7. The doctor, who when he controls a patient takes his temperature.
8. The melting of a unit of mass of a solid substance, when the body passed through the heat of fusion.
9. Physical exercise, which allows you to burn calories.
10. Heat that expels a running engine.
11. The water when it boils, because it exceeded 100 ° C.
12. In solids with a rod, heat spreads to the rod.
13. A stove.
