WebScientists define heat as thermal energy transferred between two systems at different temperatures that come in contact. Heat is written with the symbol q or Q, and it has units of Joules ( \text J J ). Heat is transferred from the surroundings to the ice, causing the phase change from ice to water.

WebWe lectured on Ch 14 (water, phase changes heating curve, cooling curve, heat of fusion, heat of vaporization, specific heat) Webtime is called a heating curve. Let's look at the heating curve for water. Heating Curves Notice that, in general, the temperature goes up the longer the heating continues. However, there are two horizontal flat parts (segments BC and DE) to the graph. These happen when there is a change of state. The plateaus are also called phase changes.
