a. Final pressure= 5atm

b. Work done = 5000 Joules

<h3>How to determine the parameters</h3>

Given;

In adiabatic expansion, temperature is constant

P1V1 = P2V2

Now, let's substitute the values into the formula

6 × 500 = 1500 P2

300 = 1500P2

Make 'p2' subject of formula

P2 = 1500/300

P2 = 5 atm

The formula for work done is given as:

Workndone = P ∆ volume

Work done = 5 × ( 1500 - 500)

Work done = 5 × 1000

Work done = 5000 Joules
