Question

Which statement would be the most useful for deriving the ideal gas law?
a.Volume is directly proportional to the number of moles.
b.Volume is inversely proportional to the temperature.
c.Pressure is directly proportional to the volume.
d.Pressure is inversely proportional to the number of moles.

Answer 1

option (a) volume is directly propotional to the no. of moles

Answer 2

Answer: The correct option is (a).

Explanation:

According to ideal gas equation:

                                        PV=nRT

Option(a) is in accordance with ideal gas equation that is volume of gas is directly proportional  to the number of moles of the gas.

Option(b) is not in accordance with ideal gas equation which says that volume of gas is directly proportional  to the temperature.

Option(c) is not in  accordance with ideal gas equation which says that pressure of gas is inversely proportional  to the volume of the gas.

Option(d) is not in accordance with ideal gas equation which says that pressure of gas is directly proportional  to the number of moles of the gas.
