A man 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 was (were):

temperature and number of gas molecules

pressure only

number of molecules only

volume and pressure

none of the above

PV = nRT. Assuming it doesn't leak, volume and number of gas molecules remain constant. So I say (drum roll) none of the above!

Answer: The correct answer is none of the above.

Explanation: There are 4 variables to define the system: Volume, Pressure, Temperature and Number of molecules.

When the man went to the gas station to inflate the low front tire, some of the variables were constant. As the gas is filled in the tire, number of molecules and pressure increases.

As, the volume of tire is fixed, so it will be the constant and temperature of the system will also remain constant.

From the given option in the question, none of the options matches the constant. Hence, the correct answer is none of the above.
