Lesson: Entropy Change in a Thermodynamic ProcessPhysics
In this lesson, we will learn how to calculate the change in the entropy of a system that results from various thermodynamic processes.
Sample Question Videos
Find the entropy change of 20 g of steam at a temperature of when it condenses to water at the same temperature. Use a value of 2,257 kJ/kg for the latent heat of vaporization of water.
A cube of ice with a mass of fifty grams and at a temperature of is allowed to melt to become water and then to boil to become water vapor at . What is the change in entropy of the water in this process?
joules of heat is removed from a heat reservoir at a temperature of K. What is the entropy change of the reservoir?
