(d) The boiling of water at 100 C and 1 atm is spontaneous. All gases at the same temperature have the same average kinetic energy. Why does temperature remain constant during phase changes? The 'heated' gas spreads out so its density decreases. When they are heated to gas-phase temperature, even these forces are overcome and the particles move as far apart as possible -- the iconic "fill the container" behavior of a gas. The average speed of the molecules is the same before and after a phase change, and so is the average kinetic energy. . Liquids have a define volume. 2. If the temperature is decreased,it is the opposite. When a certain temperature threshold unique to each substance in the universe is crossed, a phase change will result, changing the state of the matter.

Therefore, as temperature increases, so does kinetic energy. Boiling point : The temperature at which a liquid boils and changes rapidly into a gas at atmospheric pressure, is called boiling point of the liquid. It follows that the temperature of the mix is roughly 0. If the substance has enough energy, it can overcome the bonding forces holding the particles together and, in doing so, undergo a change in state. Most substances become gases at high enough temperatures given sufficient empty space. How does temperature affect particle speed? A substance to change state from a gas to a liquid or from a liquid to a solid. The temperature that we measure is not caused by the atoms themselves, but rather their random motions in the object: the faster the random velocity of the atoms, the higher the temperature. What are some examples of properties of liquids? Tony is the founder of Gie.eu.com, a website dedicated to providing information on renewables and sustainability. As temperatures increase, additional heat energy is applied to the constituent parts of a solid, which causes additional molecular motion. Here, too, the temperature remains constant at 100C until all the water has been converted to steam. Why were Mexican workers able to find jobs in the Southwest?
