Question

which of the gas laws we have studied to you see in action? \pouring liquid nitrogen on a balloon\ a pascals principle b charles law c gay lussacs law d boyles law

Explanation:

When liquid nitrogen is poured on a balloon, the gas inside the balloon cools down. Charles' Law states that the volume of a gas is directly proportional to its temperature (at constant pressure). As the temperature of the gas in the balloon decreases, its volume also decreases. Pascal's Principle is about pressure in fluids, Gay - Lussac's Law relates pressure and temperature at constant volume, and Boyle's Law relates pressure and volume at constant temperature. Here, the key relationship is between volume and temperature, which is Charles' Law.

Answer:

B. Charles' Law
