there are three ways by which we can transfer heat from one place to other
1. Conduction
In this method of heat transfer heat can be transferred from one place to other without actual movement of medium molecules. This is possible in solid conducting mediums
2. Convection
Here heat energy is carried away along with the medium molecules where medium molecules can move from one place to other while heat is transferred. It is possible in liquid and gas but not possible in solids
3. Radiation
In this mode of heat transfer we do not require any medium and here heat transferred by electromagnetic waves
So we can feel heat from sun in form of electromagnetic waves and it is the fastest way to transfer the heat also it do not require any medium
