What makes water evaporate faster in a baking sheet? Does water evaporate quicker if you mix it with alcohol? TL;DR: When trying to make water evaporate quickly, it is best to spread the water over a large surface area and apply heat as evenly as possible. In order for water molecules to change from liquid to gas, they must be directly exposed to a source of heat. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Evaporation occurs when energy (heat) forces the bonds that hold water molecules together to break. The process of evaporation is so great that without precipitation runoff, and groundwaterdischarge from aquifers, oceans would become nearly empty. Put the pan containing the salt solution on the baking sheet somewhere in a warm place like outside in the sun, or near the window. The amount of water in the air as a fraction of the total amount the air can hold when it is saturated is called relative humidity. Precipitation from those clouds fills lakes, rivers, and streams with fresh water. Then came a shocking discovery, Montana Rep. Zooey Zephyr sues over removal from House floor, Trump accuser says many in her generation didnt report rape, Mexico immigration agency head to stand trial in deadly fire at detention center, Hospitals that denied emergency abortion broke the law, U.S. says. If you're trying to make water evaporate quickly, whether for a science experiment or other reason, then several factors must be taken into account.
