Question
A noble gas has a heat capacity of Cp=1.219 J/g-K. The enthalpy decreases with respect to pressure at a rate of 20 J/g- bar at 298.15 K. The Joule Thomson Coefficient in K/bar is: a. 16.41 c. 0.041 b.-16.41 d. -0.041 2 moles of ideal gas initially at 30 °C with Cv= 2.315 J/mol-K is heated to and expands at constant pressure in a closed cylinder with a moving piston. If the final temperature is 50 °C, calculate the amount of heat added. a. 212.6 J c. 46.3 J d. 92.6 J b. 425.16 J
