Final answer:
The work done by the gas during the process b → c can be calculated using the formula: Work = Pressure x Change in Volume. If the pressure and change in volume are given, we can plug the values into the formula to find the work done by the gas.
Step-by-step explanation:
The work done by the gas during the process b → c can be calculated using the formula:
Work = Pressure x Change in Volume
In this case, we need the pressure and the change in volume for the process b → c. If this information is provided, we can plug the values into the formula to find the work done by the gas.
