The sun is entirely made up of two gases called hydrogen and helium which are also the lightest elements in the universe. The sun is mostly made up of hydrogen which occupies 72 percent of the Sun's mass whereas helium consists of the remaining 26 percent followed by other elements.

35. How can we use the Sun s energy
Sun's energy can be harnessed in many ways. People are moving towards natural sources of energy such as Solar Energy which causes zero pollution. This solar energy due to its heat can be used for heating purposes. Hence solar cookers and water heaters apply the same principle. Solar cells are available nowadays which trap sun's light and convert this into electric energy.
