Answer 2

Calculation of Work Done by Gas

To calculate the work done by a gas when its volume changes at constant pressure, we can use the formula:

Work = Pressure x Change in Volume

In this case, the pressure is given as 1 MPa (megapascal), and the change in volume is from 2 liters to 10 liters.

Using the formula, we can calculate the work done by the gas:

Work = 1 MPa x (10 liters - 2 liters)

Work = 1 MPa x 8 liters

Therefore, the work done by the gas is 8 MPa·liters.

Please note that the unit of work is MPa·liters, which is the product of pressure (MPa) and volume (liters).
