Two moles of helium are initially at a temperature of 24.0 ∘C and occupy a volume of 2.50×10−2 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. Part A What is the total heat supplied to the helium in the process? Part B What is the total change in internal energy of...

A flexible balloon contains 0.355 mol m o l of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7050 cm3 c m 3 and a temperature of 28.0 ∘C ∘ C . The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K C p = 33.26 J / m o...

A Flexible Balloon A flexible balloon contains 0.315 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7400 cm and a temperature of 29.0°C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp = 33.26 J/mol. K and y = 4/3. Part A What is the total heat...

We have seen that the Carnot cycle can be used to determine the maximum efficiency of a heat engine. The efficiency is defined as the sum of all of the work during the cycle divided by the amount of heat exchanged during the expansion process: efficiency=?1 +?2 +?3 +?3 /?1 Theoretically, the efficiency of the engine can be determined with the hot and cold temperature of the cycle. efficiency = ?h − ?c/ ?h In this problem, we will calculate...

A cylinder with a piston contains 0.140 mol of nitrogen at 1.88 105 Pa and 325 K. The nitrogen may be treated as an ideal gas. The gas is first compressed isobarically to half its original volume. It then expands adiabatically back to its original volume, and finally it is heated isochorically to its original pressure. PLEASE do B and C and don't don't forget to show all the steps specially for B becuase I don't know how to do...
