when the temperature crosses the boiling point of that liquid. it any state of matter (solid, liquid, or gas), the molecules that make up this matter are at a certain speed. To change one's state of matter, you must change it's temperature. For Example, H2O can be any state of matter. As a solid, ice, the molecules are stopped or moving very slowly, which makes it a solid. To speed up the molecules, you apply heat, which in turn, makes the ice, water, a liquid. To heat again would make the water a gas, water vapor. The same thing works reversed. The water vapor is hot, and so it is attracted to something cold, such as a mirror when you take a hot shower. This act, condensation, is also responsible for water on the side of a drinking glass. Once the hot vapor touches the hot object (think about cooking with a lid), it becomes instantly colder, and it becomes water again. To freeze it could make (as shown in the water cycle), ice, snow, or sleet, once again, making it a solid. I hope this answered your question.Depends what liquid you are talking about. Each chemical and element has a different temperature in which it turns from liquid to gas. Water goes at 100 Degrees C, something else is completely different.The boiling point also varies depending on where you are in relation to sea levelwhen it is heated above its boiling point.the molecules in liquid gets separated when energy is supplied. in form of heat if you supply above the boiling point the molecules will be more separated such that their state of matter changes and attains the gaseous stateAt the vaporization point of said liquid. For instance water vaporizes at 212 degrees Fahrenheit or 100 degrees Centigrade. This is at sea level, higher elevations make for lower temperatures because of less pressure. Like I've taken the temp of boiling water here in Salt lake at an elevation of somewhere around 5000 feet and it boils closer to 198 or so. And of course different elements vaporize at different temperatures, so it really depends on what and were, and possibly who as well.
