Which of the following statements are true? (Select all that apply.)
When the temperature change during a process is large and the specific heats vary nonlinearly with temperature, the constant-specific-heat assumption is preferred. -Errors introduced by the constant-specific-heat assumption are minimized when the specific heat values are evaluated at room temperature. -When the specific heats are independent of temperature, the constant-specific-heat assumption produces exact answers. -For monatomic ideal gases, the constant specific-heat assumption introduces no error. -The accuracy of using the constant-specific-heat assumption is usually sufficient if the temperature range is not greater than a few hundred degrees.
