A clip-on propane regulator. Typical bottles sizes vary from 3.9 kg to 13 kg but note that those are the weights of the amount of gas in the bottles, not the total weight.
Water vapor is another greenhouse gas that keeps heat from the sun trapped in the Earthâs atmosphere and helps maintain a temperature at which life can flourish on our planet. However, deforestation also affects the amount of this in the air.
Have you ever wondered how much water vapor is in the Earth's atmosphere or what the maximum amount is that air can hold? Here's the answer to the question. Answer: Water vapor exists as an invisible gas in air. The amount of water vapor in air varies according to the temperature and density of air. The amount of water vapor ranges from a trace amount up to 4% of the mass of air. Hot air can hold more water vapor than cold air, so the amount of water vapor is highest in hot, tropical areas and lowest in cold, polar regions.
