Climate change poses a fundamental threat to the places, species and peopleâs livelihoods WWF works to protect. To adequately address this crisis we must urgently reduce carbon pollution and prepare for the consequences of global warming, which we are already experiencing. WWF works to:
How does your air conditioner manage this? In a similar way to how your refrigerator manages to stays cold, but minus the insulated box. A nonflammable gas, known as Freon, undergoes an evaporation process again and again within most refrigerators in order to keep the temperature low. The same cycle is used for air conditioners. This is how it works: First, a compressor in your air conditioner compresses cold Freon gas. A small amount of oil is combined with the Freon gas to lubricate the compressor. When the Freon gas is compressed, its pressure rises, making it very hot.
Evaporation is a liquid that occurs from the surface of a liquid  into a gaseous phase. This type of liquid vaporizes. when water turns to steam or air only fomr the top.he water vapor (air) will rise into the clouds as a gas. This is known as evaporation. When the clouds fill up with enough water, it starts to rain. This is known as condensation. The water goes back into the pool. So you never lose any water, it comes back. This is known as the water cycle.
