The common misconception of heat energy and difference between heat and temperature.

 We are generally thinking about heat and temperature both are the same but actually heat is energy and temperature is the measurement of heat quantity.

And also we thought that heat needs some medium to contact and transfer its energy like sound. But radiation does not compulsion for medium for the transfer of energy. Without any medium heat can radiate from one place to another place. For instance sun radiation.

Another general mindset of common people, boiling water can cause a big effect of heat rather in reality steam causes much more effect of heat than boiling water.



The above concept is simplified in the below tabular column.

Common Misconception

Fact

Heat and temperature are the same.

Heat is a form of energy. Temperature is a measure of the degree of hotness or coldness of a body.

Transfer of heat from one body to another needs a medium.

Radiation of heat does not require any physical medium. (Example: Heat from sun reaches earth through vacuum)

Boiling water can cause more damage.

Steam causes more damage due to latent heat as compared to boiling water.

 Difference between Heat and Temperature

Heat is an energy temperature is a measurement of the quantity of heat. Heat is an energy, work, and causes some effect but temperature is just like mathematical measurement work.

Heat

Temperature

Heat is a form of energy

Temperature indicates the thermal condition of a body i.e., how hot (or) how cold the body is?

Heat is the cause

Temperature is the effect.

Heat contents of a body do not decide the direction of heat flow from the body.

The temperature of a body decides the direction of heat flow from the body.

S.I. unit of heat is joule (J)

S.I unit of temperature is Kelvin (K)

 


These are the measuring scales for temperature which are widely using all branches of science and technology.  The SI unit of temperature is Kelvin but we also use Fahrenheit and Celsius for many other temperature measurement processes.
