Answer 2

Calculation of Work Done by the Gas

To calculate the work done by the gas, we can use the first law of thermodynamics, which states that the change in internal energy of a system is equal to the heat added to the system minus the work done by the system.

Given: - Change in internal energy of the gas = 100 kJ - Heat added to the gas = 400 kJ

We can use the equation:

Change in internal energy = Heat added - Work done

Substituting the given values:

100 kJ = 400 kJ - Work done

Now, let's solve for the work done by the gas:

Work done = Heat added - Change in internal energy Work done = 400 kJ - 100 kJ Work done = 300 kJ

Therefore, the work done by the gas is 300 kJ.
