Given a cylinder of fixed volume filled with 1 mol of argon gas, which of the following is correct? (Assume all gases obey the ideal gas law.)

Question

Quizplus · Accepted Answer

The volume of the cylinder is fixed, so adding a second mole of argon will increase the pressure and temperature, and therefore the ratio T/P will not remain constant (choice A is incorrect). According to the ideal gas law, pressure is directly proportional to temperature and thus doubling the temperature will double the pressure, so choice B is incorrect. The number of gas atoms in a cylinder of equal volumes and pressure will be the same regardless of the type of gas, as the volume and pressure are the only variables in the ideal gas law, so choice C is also incorrect. Therefore, the best choice is E, none of these is correct.
