Problem 38P

IP A cylinder contains 18 moles of a monatomic ideal gas at a constant pressure of 160 kPa. (a) How much work does the gas do as it expands 3200 cm3, from 5400 cm3 to 8600 cm3? (b) If the gas expands by 3200 cm3 again, this time from 2200 cm3 to 5400 cm3, is the work it does greater than, less than, or equal to the work found in part (a)? Explain. (c) Calculate the work done as the gas expands from 2200 cm3 to 5400 cm3.

Solution 38P

Step 1 of 4

Here, we have to calculate the work done by a monoatomic gas in constant pressure expansion processes.

The equation for the work done by a gas,

Where, - Pressure of the gas

- Change in volume

a)
