Question 10

A fixed mass of gas is enclosed in a cylinder by a gas-tight piston. The initial pressure of the gas is 1.5 × 105 Pa. The piston is slowly pushed inwards at a constant temperature, reducing the volume of the gas by 40% of its initial value.

What is the new pressure of the gas?

A

9.0×104 Pa9.0 \times 10^4 \text{ Pa}9.0×104 Pa

B

2.5×105 Pa2.5 \times 10^5 \text{ Pa}2.5×105 Pa

C
