WebAnalysis of the cooling curves. First attempt The result of the rate of cooling for stearic acid in the first attempt was 4 °C/min at the start of the cooling curve and at the end of the cooling curve it was 1 °C/min. This is the second graph as shown above with the digital thermometer that was used to measure and record the temperature. WebNov 15, 2024 · Heating and cooling curves are graphs of temperature over time for different substances, demonstrating the phase changes.

WebA cooling curve of a substance is a graph of the variation of the temperature with time as it is allowed to cool. The gradient of the cooling curve is related to the heat capacity, the thermal conductivity of the substance, and the external temperature. The more heat is required to change the temperature of the substance, the slower it cools ... WebApr 18, 2006 · How Heating and Cooling Systems Work. All climate-control devices or systems have three basic components: a source of warmed or cooled air, a means of distributing the air to the rooms being heated or cooled, and a control used to regulate the system (e.g., thermostat). The sources of warm air, such as a furnace, and cool air, such …
