What is water vapour?
Answers
Answer:
water in gaseous state
Answer:
When an object is cool and warm air touches the cool object, the air cools and droplets of water form on the outside of the object. This is the result of the hot and cold air coming into contact with each other. This water in the air is called water vapour. Water vapor is in the form of a gas. Characteristics of water vapor include it being colourless, odourless, invisible, and has no taste. Humidity is the amount of water vapor in the air. When the air turns into a gas it is called evaporation. Water vapor gets into the air day through the process of evaporation. Ocean water, and other bodies of water, is turned into water vapor using the energy from the sun. The molecules of the water are absorbed by the Sun's energy near the surface of the water, which then evaporates into the air. The changing of a gas into a liquid is called condensation. An example of condensation is the water, which covers a mirror following a hot shower. Another large source of water vapor in the air is when the plants absorb water through their roots and stems into their leaves. The leaves then give off water. The process of plants releasing water into the air is called transpiration. All of the water in the air, whether it is from the world's ocean and other bodies of water, the water on a mirror following a hot shower, or the water a plant releases into the air; it is all called humidity because it is the amount of water vapor in the air.
