WebA phase diagram indicating the temperature changes of water as energy is added is shown in Figure 11.11. The ice starts out at −20 °C, and its temperature rises linearly, absorbing heat at a constant rate until it reaches 0 °. Once at this temperature, the ice gradually melts, absorbing 334 kJ/kg. WebLatent heat (also known as latent energy or heat of transformation) is energy released or absorbed, by a body or a thermodynamic system, during a constant-temperature process — usually a first-order phase transition..

WebWhen the phase change occurs, there is a "thermal arrest"; that is, the temperature stays constant. This is because the matter has more internal energy as a liquid or gas than in … WebLatent Heat Previously, we have discussed temperature change due to heat transfer. No temperature change occurs from heat transfer if ice melts and becomes liquid water (i.e., during a phase change). For example, consider water dripping from icicles melting on a roof warmed by the Sun.

Weblatent heat, or sometimes, a heat of transformation; we will say more about them later on. For now, note that when a pot of water boils, what happens is that the heat from the burner is absorbed by liquid water; as it absorbs the latent heat, the water is transformed into vapor (bubbles), which rise to the top and disperse. This process takes ...
