Question 8

During a seabed survey, gas is collected in a flexible chamber at a pressure of 5.0 × 105 Pa. The gas occupies 0.020 m3. At the surface, the gas is at a pressure of 1.0 × 105 Pa. The temperature and mass of the gas stay the same. Use the equation P1×V1=P2×V2P_1 \times V_1 = P_2 \times V_2P1​×V1​=P2​×V2​.

Calculate the volume of the gas when it reaches the surface.
