Liquid Nitrogen and Balloons

If you have not yet watched the video above you watch it now. As you might have noticed, when you place a balloon into a liquid nitrogen it compresses and when it dries it inflates back to its original form. Liquid nitrogen is a nitrogen but in liquid form and it is in a very low temperature. This means that liquid nitrogen are too cold that it causes rapid freezing when it touches a living tissue. When a gas is cooled down enough, the space that the gas occupies decreases. This state is popularly known as "Charle's Law" which states that the volume it occupies increases if the temperature increases. When the balloon is heated up, the gas inflates and increases in volume.
