Question

1.A small research submarine with a volume of 1.2 x 105 L has an internal pressure of 1.0 atm and an internal temperature of 150 C. If the submarine descends to a depth where the pressure is 150 atm and the temperature is 30 C, what will the volume of the gas inside be if the hull of the submarine breaks?

Answer 1

Initial pressure of the gas , P = 1.0 atm Initial temperature, T= 15°C +273 = 288 K Initial volume of the gas, Vj = 1.2x10 L Final pressure of the gas , P = 150 atm Final temperature, T, = 30 °C +273 = 303 K According to the ideal gas equation, -11 Final volume of the gas, (1.0 atm)(1.2x10ʻL) (288 K) = 8.42x10'L = 842 L (303 K) (150 atm)
