An ideal gas is sealed within a container that prevents the gas from expanding under any circumstances. Heat is continually added to the gas for a period of time. Which one of the following statements best describes this thermal process that occurs in the time from before the addition of heat to the time when heat is no longer added? The internal energy of the gas decreases during this process. The temperature of the gas remains constant during this process. No work is done by the gas during this process. Positive work is done by the gas during this process. The internal energy of the gas is constant during this process.
Suppose 4.29 moles of a monatomic ideal gas expand adiabatically, and its temperature decreases from 413 to 272 K. Determine (a) the work done (including the algebraic sign) by the gas, and (b) the change in its internal energy. (a) Number Units (b) Number Units
One-half mole of a monatomic ideal gas absorbs 1150 J of heat while 2160 J of work is done by the gas. By how much does its temperature change in kelvins? Use the proper sign to specify whether the change is an increase or a decrease. Number Units :
Current Attempt in Progress The temperature of 1.97 mol of a monatomic ideal gas is 372 K. The internal energy of this gas is doubled by the addition of heat. How much heat is needed when it is added at (a) constant volume and (b) constant pressure? (a) Number Units (b) Number Units
