Difference between heat and temperature in tabular form
We often talk about heat and temperature in our daily life in this article we discus about the Difference between heat and temperature in tabular form. In terms of weather, or sometimes in terms of temperature. But do we know the difference between heat and temperature? It is important to realize the smallest difference between the heat and temperature scales to measure the heat or coldness of any object.
They are interconnected, but contrary to popular belief, they do not mean the same thing. Knowing the distinction between heat and temperature can lead to a clearer understanding of the world around us. In this article, we will define both heat and temperature and come to understand how they are related, but not identical.
Heat vs temperature Difference between heat and temperature in tabular form
The heat is the total energy of the movement of molecules of a substance, while the temperature refers to the measure of the average energy of the movement of molecules in the substance. The heat depends on factors such as the speed of the particles, the size of the particles and the number of particles, etc.
The temperature , on the other hand, is independent of these factors. For example, let’s compare a tub of water to a cup of water. The water in the tub and the bowl may be at the same temperature, but due to the number of particles in the tub, the water in the tub has more thermal energy and therefore more heat even though they are the same temperature.
A temperature is a number that is related to the energy possessed by the molecules of a substance, which is directly related to the kinetic energy possessed by the particles of the substance. The SI unit of temperature is degrees, Kelvin. As we said before, temperature is directly related to the kinetic energy of molecules, therefore, if you double the temperature (in degrees Kelvin) of a substance, you double the average kinetic energy that those molecules possess.
Comparison table between heat and temperature
|Definition||The heat of an object is the total energy of all molecular motion within that object.||Temperature is the measure of the thermal energy or the average heat of the molecules of a substance.|
|Unit||Joules, Calories||Fahrenheit, Celsius, Kelvin|
|Particles||Heat is a measure of the number of atoms multiplied by the energy that each atom possesses.||It is like a level that determines the direction in which the heat will flow. It is related to how fast the molecule moves within a substance.|
|Ability to work r||Has the ability to work.||Temperature can be used to measure the degree of heat.|
Let’s take a closer look at heat and temperature now. When you add heat to a substance, you are giving it energy. There are two things that can happen when you heat a substance;
- Substances experience an increase in temperature corresponding to the increase in the kinetic energy of the molecules; that is to say, the heat gives the molecules extra energy to move with more speed, and this increase in speed implies an increase in temperature. Molecules now travel faster than before they were supplied with heat.
- The substance can also undergo a phase or state change; for example, at a certain temperature, that is, 100 o C or 373 o K, with the addition of more heat, the water molecules begin to come out in a state of vapor. This is called a phase shift . One thing we must remember is that the energy added to change the state of a substance does not result in an increase in temperature, that is, if we have a cup of water at 90 o C, the addition of heat will cause this temperature to rise to 100 o C, if we keep adding heat, the water turns into water vapor with a temperature of 100 o The energy absorbed in phase changes is not used to increase the temperature but is used to change the phase and is called the latent heat of vaporization.
