# A small research submarine with a volume of 1.2x10 ^5 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?

The answer is

The best way to approach this problem is by using the combined gas law

**assuming** the number of moles remains constant. Knowing that

Notice how both a significant increase in pressure and an important drop in temperature contributed to the massive drop in volume the submarine underwent.
