In one or two sentences, describe a scenario using the combined gas law in which changes occur in the pressure and temperature of an enclosed gas but the volume does not change.
A balloon filled with air is placed in a room where the temperature decreases, causing the gas particles to slow down and the pressure to decrease, but the volume of the balloon remains the same.
A propane tank is placed outside on a hot summer day; as the temperature increases, the pressure inside the tank also increases according to the combined gas law, while the volume remains constant.
One possible scenario could involve a scuba diver descending into the ocean depths, where the pressure increases due to the weight of the water column, while the temperature remains constant since water conducts heat more efficiently than air, resulting in the volume of the diver's scuba tank remaining unchanged. To use the combined gas law to calculate the final pressure or temperature, we need to know the initial pressure, temperature, and volume of the gas.
