In the real world, many situations will involve both the sensible heat equation and the latent heat equation. Example 1: How many BTUs are required to change 5 pounds of 100ºF water into 212ºF steam? Before solving this problem, it is essential to recognize that there are two distinct components. First, the temperature of the […]

When a substance changes state from solid to liquid, or from liquid to vapor, it is said to undergo a phase change. Interestingly, as heat is applied or removed from a substance during a phase change, the temperature of the substance remains constant. For example, when a block of ice melts to form water, the […]
Oftentimes, heat gains and losses can be measured with a thermometer. When this is the case, the heat can be “sensed” and we call it “sensible heat”. Raising the temperature of water from 20ºF to 40ºF is an example of sensible heat. The formula used to calculate the heat required to raise the temperature of […]
Have you ever wondered why some things heat up quicker than others? Or why some substances might take several minutes to get hot, while others only take a few seconds? It is well understood that as heat is applied to a substance in a single state, the temperature of the substance will increase. Experiments have […]
