A sealed cylinder of gas contains nitrogen gas at 101.3 kPa and 20.0 degrees Celsius. When the cylinder is left in the sun, the temp of the gas increases to 50.0 degrees Celsius. Find the new pressure of the gas in the cylinder.

According to Boyle's Law,
                                        " the volume of a fixed mass of gas is inversely proportional to the pressure applied on it'.

Mathmatically,
                                    V ∞ 1 / P
Or,
                                    V = k / P
Explanation:
                   The balloon filled with Neon gas outside the chamber will have greater volume than in the chamber because the pressure in the chamber is high as compared to outside. So, the outside force brings the molecule of gas to get closer to each other.
