WebPhase diagram of water. The temperature on the y-axis and heat input on the x-axis. Below 0C is ice, 0C to 100C is liquid water and above 100C is water vapor. Starting below 0C as heat is added the line rises steeply to … 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.
