Liquid water has more entropy than ice not because the molecules are farther apart, but because they arranged and oriented more haphazardly. You can see this in the diagram below. A Mass depends on the force of gravity. Freezing means solidification. Supplying heat basically means increasing temperature (provided it is not being utilized for doing work).Now this means we need to understand what is temperature?Temperature is related to average kinetic energy of particles.Supplying heat increases temperature which means AVG kinetic energy increases - Polario Mar 27, 2018 at 14:00 Add a comment B. state of matter. The water and the ice have roughly the same temperature. Answer (1 of 3): Higher temperatures cause the atoms and molecules of solid objects to vibrate more energetically around their equilibrium points. Press ESC to cancel. To followup on other answers, there is no guarantee that particle (molecule or atom) spacing will increase. When the temperature of the water reaches 100C, the water begins to boil. This relationship between kinetic energy and temperature is known as the kinetic theory of matter. I'm going to argue that the distance between molecules does generally increase with temperature for very fundamental reasons, although normal ice (Ih) and liquid water are an exception.

Such an absolute "zero point" is used for the so-called Kelvin scale. Which has a bigger volume solid, liquid or gas? A metal spoon heating up in a pot of boiling water. When you hit the melting temperature, the heat you put in goes towards the enthalpy of melting, and starts converting ice (sold) to water (liquid). As the temperature increases, the average kinetic energy of the particles also increases. The actual average speed of the particles depends on their mass as well as the temperature heavier particles move more slowly than lighter ones at the same temperature. If the temperature around a solid is raised very quickly, it can sublimate, or phase change from a solid to a gas without existing as a liquid. Weight is always the same. Which is greater 36 yards 2 feet and 114 feet 2 inch? All three states of matter (solid, liquid and gas) expand when heated. Edit. Weight depends on the force of gravity.
