Heat and temperature they have already been confused with the same thing, it is therefore necessary to distinguish the two to bring a clear picture of the phenomena. They may look similar, but they are very different according to science and research.
Heat is a type of energy that measures the total kinetic energy of molecules in a body, while temperature is the hot or cold state of matter. Heat measurements are in Joules (J).
On the other hand, temperature measurements are in degrees Celsius (°C). It can also be measured in Fahrenheit (°F) or Kelvin (K), depending on the institution or country. Heat is expressed as Q, while the expression for temperature is T. A thermometer is used to measure temperature, while a colorimeter measures heat.

What is temperature?
Absolute zero is the temperature theoretically minimal, in which the particles remain immobile. Absolute zero is 0 K (Kelvin scale), -459.67°F (Fahrenheit scale) and -273.15°C (Celsius scale). Most of the world uses the Celsius scale, but the United States generally uses the Fahrenheit scale.
In science, the Kelvin scale is widely used in measurements and was named after a Scottish physicist. The Kelvin scale is more commonly called the 'absolute scale'.

O heat it can be transferred through radiation, conduction, convection and advection. Conduction is the transfer of heat between solids, radiation is the transfer of energy in the form of electromagnetic waves through air, or a medium and the convention is a heat transfer in liquids and gases.
Advection, on the other hand, is the transfer of heat by the flow of fluid from one point to another. Heat is in simple terms transferred from a hot spot to a less hot spot, independently or through a medium.
The agitation of the matter particles increases when there is heat transfer. Latent heat is the amount of heat needed to turn a solid into a liquid or steam, or change the fluid to steam without necessarily changing the temperature.
Relationship between heat and temperature
When trying to understand the concept of heat and temperature, what is important to note is that heat will raise or lower the temperature. An increase in heat will lead to an increase in temperature, while a decrease in heat will cause a decrease in temperature.
Another critical difference is that heat is energy, while temperature is just a measure of energy. Mainly, the increase in heat causes an increase in the volume of matter. A quick example is a bathtub full of water and a glass full of water. Despite being at the same temperature, the two can vary in terms of heat.
The bathtub has more water molecules, and that translates to more heat energy, leading to more heat generation. This is why the cup may have cold water as opposed to the bathtub which has warmer water despite the fact that both are at the same temperature.
Temperature takes into account changes in the phases or states of matter. Boiling, evaporation, melting and freezing are all processes affected by changes in temperature. Heat and temperature are actually different, but casually mistaken for the same thing.
