Nuclear Power Plant uses a Non Renewable Energy Source.
Non-renewable energy is that source of energy which can not be used again and again. This sort of energy is sustainable to exhaustion.
Non renewable energy is that form of energy which is subject to deletion. This type of energy is of many uses to us. It can be used to produce electricity, heating, cooking, transportation and manufacturing. 85% of the energy used in the industrial processes is form the non-renewable type of energy.
The amount of water vapor ranges from a trace amount up to 4% of the mass of air. Water vapor exists as an invisible gas in the air.
The amount of water vapor in the air is called absolute humidity. The amount of water vapor in the air as compared with the amount of water that the air could hold is called relative humidity.
The maximum amount of water vapor that can be in the air depends on the air temperature.
