The temperature will only remain constant whilst the heat source is still being applied. The melting point is the temperature at which, under the given circumstances, a compound changes it’s physical state from solid to liquid. The example we will use here is ice melting into water. Answer to: Why does temperature remain constant for melting ice? [Pure] Ice melts at 0C, period. The temperature of the water will not exceed 100 degrees because above this the water will no longer be a liquid, it will be in a gaseous state (steam). And melting of ice at constant temperature (0 deg) is an equilibrium state which shifts depending on the energy provided only No, it isn't/doesn't. 4.when water freezes the temperature remains constant at 0*c and yet the water is giving off heat constantly.why? So, until all the ice has melted, the heat absorbed does not raise the temperature of the ice-water mixture. Once you get the ice up to zero C, having put in 0.5 calories per gram per degree to get it up to 0 C, you still have to add 79.7 calories per gram to melt the ice. ... and move around freely to form the liquid form, water. Note: The above explanation is borrowed from this Link A common misconception is that salt actually warms up the ice and causes it to melt. Take water for an example. Nevertheless, the principle is the same. Why does the temperature remain constant during the melting of ice even though heat is supplied continuously? Increasing or decreasing the heat flux does not change that, it only changes the speed at which it melts. This is because the energy added here is only breaking the bonds between the water molecules, allowing the ice to … Solid ice is heated and the temperature increases until the normal freezing/melting point of zero degrees Celsius is reached. Sometimes, the phase change is from a solid to a gas, such as when dry ice turns into carbon dioxide. https://sciencing.com/happens-temperature-ice-melts-8432055.html 5.suppose water in a plastic pail is left outdoors on a cold night when the temperature drops from 12*c to -8*c.explain what happens to the molecules of water. Immediately after the molecular bonds in the ice are broken the molecules are moving (vibrating) at the same average speed as before, so their average kinetic energy remains the same, and, thus, their Kelvin temperature remains the same. 3.why does the temperature of melting ice remains constant? Also, a solid may change into another solid by phase change, such as when one form of ice changes into another, but this does not happen under normal atmospheric pressure and temperature.
