Question 1
A gas expands as shown in the graph. If the heat taken in during this process is 1.02
× 10
6 J and 1 atm = 1.01
× 10
5 N/m
2, the change in internal energy of the gas (in J) is
◦ −2.42 × 106
◦ −1.40 × 106
◦ −1.02 × 106
◦ 1.02 × 106
◦ 1.40 × 106
Question 2
A gas expands from A to B as shown in the graph. Calculate the work (in joules) done by the gas. (1 atm= 1.01
× 10
5 N/m
2.)
◦ 12
◦ 24
◦ 1.21 × 106
◦ 2.42 × 106
◦ 3.64 × 106
