Aballoon is filled with neon gas. what will happen to the balloon after it is put into a chamber whose pressure is more than the atmospheric pressure, as the temperature remains constant.

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.

A. volume stays constant. just took took the quiz

They are all decomposition reactions.
