2. When Susie puts the balloon in hot water, she will observe the expansion of the balloon.
What is Charles's law of gas?
According to Charles' law, assuming the pressure is constant, the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature. French physicist J.-A.-C. Charles initially proposed this empirical relationship.
1. When Susie puts the balloon in ice water, the temperature of the gas inside the balloon will decreases and according to Charles' law its volume also decreases. That's why, she will observe the contraction of the balloon.
2. When Susie puts the balloon in hot water, the temperature of the gas inside the balloon will increases and according to Charles' law its volume also increases. That's why, she will observe the expansion of the balloon.
