Two moles of helium are initially at a temperature of 30.0 ∘C and occupy a volume of 3.50×10−2 m3 . The helium first expands at constant pressure until its volume has doubled. Then it expands adiabatically until the temperature returns to its initial value. Assume that the helium can be treated as an ideal gas.

A.) What is the total heat supplied to the helium in the process? In J

B.) What is the total change in internal energy of the helium? In J

C.) What is the total work done by the helium? In J

D.) What is the final volume of the helium? In cubic meters

A cylinder contains 1.5 moles of ideal gas, initially at a temperature of 113 ∘C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 6.4×105Pa on the gas. The gas is cooled until its temperature has decreased to 27∘C. For the gas CV = 11.65 J/mol⋅K, and the ideal gas constant R = 8.314 J/mol⋅K. 1.Find the work done by the gas during this process. 2.What is the change in the internal (thermal) energy of...

Initially 5.00 mol of helium (which we can treat as an ideal gas) occupies volume 0.120 m3 and is at temperature 20.0 ∘C. You allow the helium to expand so that its final volume is 0.480 m3 and its final temperature is also 20.0 ∘C. a)Calculate the net change in entropy of the helium if you make the helium expand isothermally from 0.120 m3 to 0.480 m3. b)Calculate the net change in entropy of the helium if you first increase...
