A typical scuba tank has a volume of 11 liters and can support a diver for one hour. An adult breathes about 3 liters of air with each breath. How can an 11-liter tank give a diver enough oxygen for one hour?

The correct answer is - at high pressure a huge amount of gases can be stored in less volume.

Explanation:

We already know that pressure is inversely proportional to the volume of gas which means if we increase the pressure the volume of gas becomes less.

P = 1/V

So in the scuba divers tank, the oxygen is filled at very high pressure so the high amount of the oxygen can be filled in less volume and which will last for longer than a normal pressure tank can last.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
