Aman went to a gas station and asked the attendant to inflate the low front tire. when the attendant finished, the constant(s) for the system is (are): temperature and number of gas molecules pressure only number of molecules only volume and pressure none of these choices

None of these choices

Explanation:

Generally, the properties of gas such as pressure, temperature, volume and number of moles are related. When the attendant inflated the low front tire, the volume of gas in the system changed from the initial volume. The change in volume of gas automatically change the system pressure, temperature and number of moles. The magnitude of these changes can be estimated by using the appropriate gas law. Therefore, the correct answer is the last option, i.e. none of these choices.

it's filtration, but this is an assumption so my apologies if i got this
