Four moles of an ideal monatomic gas expand isothermally at a temperature of 47 °C. If the volume of the gas quadruples during this process, what is the heat flow into the gas?
¨Calculate the entropy change when 2 moles of an ideal gas are allowed to expand isothermally from an initial volume of 1.5 L to 2.4 L. Then estimate the probability that the gas will contract spontaneously from the final volume to the initial one.
A sample of n moles of a monatomic ideal gas is expanded isothermally and reversibly at a constant temperature T from a volume V to 3V. Note that since the temperature of the gas is constant, the internal energy will remain constant. a) Write an expression for the change in entropy ΔS for the system. b) The sample has 7 moles of gas and is kept at a temperature of 305 K. The volume is changed from 0.065 m3 to...
Two moles of an ideal gas occupy a volume V. The gas expands isothermally and reversibly to a volume 6 V. A)Is the velocity distribution changed by the isothermal expansion? B)Explain why ? C)Use the equation ΔS=klnw2/w1 to calculate the change in entropy of the gas. D)Use the equation ΔS=Q/T to calculate the change in entropy of the gas. Compare the result in part (d) to that obtained in part (c).
