To reinforce what is known about the states of matter, it can be helpful to study the heat energy profile of water. The graph below shows heat, measured in BTUs, applied to a pound of water on the horizontal axis and the temperature change of the water on the vertical axis. The values displayed are […]
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 […]
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 […]
