Question

describe the various ways in heat energy can enter

Answer 1

1)Conduction-The process of transfer of heat in solids from a region of higher temp. to a region of lower temp. without the actual movement of molecules is called conduction.
2)Convection-The mode of transfer of heat in a liquid or a gas by the actual movement of their molecules from the hotter to the colder parts of the liquid or a gas is called convection.
3)Radiation-The process of transmission of heat, in which heat energy travels in lines from the hotter body to a colder body, without heating the intermediate medium is called radiation.
