(a) A tank contains one mole of oxygen gas at a pressure of 6.30 atm and a temperature of 29.5°C. The tank (which has a fixed volume) is heated until the pressure inside triples. What is the final temperature of the gas?   (b) A cylinder with a moveable piston contains one mole of oxygen, again at a pressure of 6.30 atm and a temperature of 29.5°C. Now, the cylinder is heated so that both the pressure inside and the volume of the cylinder double.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
