Example 1: In summer, when the air-conditioned outdoor environment is around 35 degrees, we can estimate the temperature at this time the condensation temperature. Because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. However, you may visit "Cookie Settings" to provide a controlled consent. If the amount of work done by a cell is the same as the amount of energy transferred in by heat, or the amount of work performed on a cell matches the amount of energy transferred out by heat, there will be no net change in internal energy.
