What are the three modes of heat transfer?

What are three types of heat transfer? “when two bodies at different temperature are in thermal contact with each other,thermal energy from a hot body flows to a cold body in the form of heat.This is called heat transfer.” Transfer of heat is a natural process.It continues all the time as long as the bodies in thermal contact are at ...

Different temperature Scales: Celsius,Fahrenheit and Kelvin conversions

Different types of thermometer¬† What is temperature in physics? “The temperature of a body is the degree of hotness or coldness of the body.”or “Average kinetic energy of atoms or molecules.”When we touch a body,we feel it hot or cold.The temperature of a body tells us how hot or cold a body is. When two systems are in thermal equilibrium,we ...
