During an isothermal process, 5.0 J of heat is removed from an ideal gas. What is the change in internal energy?
A refrigerator removes heat from the freezing compartment at the rate of 20 kJ and ejects 24 kJ into a room per cycle. How much work is required in each cycle?
An ideal gas is expanded isothermally from 20 L to 30 L. During this process, 6 J of energy is expended by the external mechanism that expanded the gas. Which of the following statements is correct?
An ideal gas is compressed to one-half its original volume during an isothermal process. The final pressure of the gas:
When the first law of thermodynamics, Q = DU + W, is applied to an ideal gas that is taken through an isothermal process:
