Question

Heat can be transferred by three methods i.e. convection, radiation and conduction. All these methods involve atoms however space is a blank place and there are no atoms so heat cannot be transferred in space. My question is that the place between earth and sun is also space so how the heat of sun is transferred to the earth.......?????​

Answer 1

Heat is transferred from sun to earth by radiation. In radiation there is no need of direct contact between the source of heat energy and the object to which heat is transferred. But conduction and convection require such contact.

Hope this helps you ☺️
