Generally a solid first converts into a liquid and then into a gas. But under certain conditions of temperature and pressure, certain compounds turn directly to gas without passing through a liquid phase first. Answer and Explanation:1
s law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be directly ...
