First Law of Thermodynamics: A cylinder contains 8.8 moles of ideal gas, initially at a temperature of 126°C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 5.3 × 105 Pa on the gas. The gas is cooled until its temperature has decreased to 27°C. For the gas Cv = 13.73 J/mol ? K. The ideal gas constant is R = 8.314 J/mol ? K. For this process, calculate:(a) the work done by gas(b) the net change in the internal (thermal) energy of the gas(c) the heat transferred to the gas.
What will be an ideal response?
An ideal gas is allowed to undergo a free expansion. If its initial volume is V1 and its final volume is V2, the change in entropy is
A. nR ln (V2/V1) B. nRT ln (V2/V1) C. nk ln (V2/V1) D. 0 E. nR V2/V1
