Although heat and temperature are related, they are not the same. When a substance, the temperature of that substance rises and therefore more heat usually means a higher temperature. In fact, many people know that the temperature rises when a body is warmer, such as when you have a fever. However, the two terminologies present differences related to our perception.
In this article you can find the differences between heat and temperature.
Heat and temperature are related
In our daily life, we often use these terms. “How hot it is today!” or “Outside 30 faC” are some examples. Without a doubt, heat and temperature are related. When we refer to temperature, we are referring to the speed at which atoms move. Heat, on the other hand, is a measure of the number of atoms in a substance multiplied by the amount of energy each atom has.
The temperature is the mean movement, and it does not depend on the number of particles in an object or its size. For example, the temperature of a glass of boiling water is the same as the temperature of a pot of boiling water, although the latter is much higher.
Heat is the amount of energy a body has, While temperature is a quantity of heat or thermal energy that can be measured by a thermometer. We don’t see heat, but we feel it, and we often use a thermometer to see if it is warmer or cooler in the environment when the heat changes the temperature.
Both are terms widely used and studied in physics, And with heat, bodies expand or change physical state. Heat changes from a warmer object to a cooler object. For example, imagine a hot cup of coffee when you add cold milk. The heat will be distributed between the two substances, and the coffee will not be as hot as if it were coffee alone, but the milk will not be as cold as if it were milk alone. As for the temperature, it rises when a substance heats up and falls when it cools.

Differences between heat and temperature
In the following lines you will find a summary of the differences between heat and temperature.
There is a thin line that differentiates heat from temperature. .Meanwhile heat is the total energy of the movement of particles found in a substance, temperature is a quantity of heat that refers to an average.
The symbols used in physics vary between the two phenomena. Heat is represented by the symbol “Q”, as has been said, it is the energy, both kinetic and potential, that molecules have in a piece of matter. In terms of temperature, is represented by the symbol “T”, And it is not energy but a measure of it.
3. Particle properties
As for the properties of particles, heat depends on speed. the number, size and type of these. On the other hand, the temperature does not depend on these qualities.
4. Its effect
Heat is a physical phenomenon that raises the temperature. It expands, melts, volatilizes or breaks down a body. Temperature is the degree of heat in bodies.
Heat is transferred from one substance to another and has an effect on the temperature difference. As I explained earlier in the latte example. In addition, this type of energy can be propagated by conduction, convection and radiation.
6. Measuring device
Heat and temperature they are measured with different measuring devices. To measure heat, a device called a calorimeter is used. However, the temperature is measured with the thermometer.
7. Units of measurement
But not only the measuring instruments are different, but also the measuring units. the heat is measured in Joules, Calories and Kilocalories. Instead, temperature is measured in Kelvin (K), Celsius (C), or Fahrenheit (F).
The Joule is the energy unit of the somewhat special international system, which measures heat, work or energy. Therefore, it is a unit of energy just like calories: 1 calorie equals 4184 joules
