Question 15

A high-performance emergency flotation pod contains a small cylinder of pressurized helium with a volume of 80 cm3.

When the helium gas is fully discharged into the flotation bladder at sea level, it expands to a volume of 760 cm3.

The ambient atmospheric pressure at sea level is 102 kPa.

Calculate the pressure of the gas when it was sealed inside the cylinder. Use the equation:

P1=P2×V2V1 P_1 = \frac{P_2 \times V_2}{V_1} P1​=V1​P2​×V2​​
