# A 2000 cm3 container holds 0.10 mol of helium gas at 300°C. How much work must be done to compress the gas to 1000 cm3 at (a) constant pressure and (b) constant temperature?

a. The value of work done at constant pressure is 240J

b. The value of work done at constant volume is 330J

See the step by step solution

## Step 1: Definition of work done

The work done has represented as energy that is transferred between system and environment.

## Step  2: Finding the work done energy.

The value of the changeable volume is

the equation of real gas is

So the work done is

Now the temperature in Kelvin is (= 573K

a. The value of work done at constant pressure

b. The value of work done at constant pressure
