For an ideal gas, classify the following pairs of properties as directly or inversely proportional? For an ideal gas, classify the following pairs of properties as directly or inversely proportional: P and T P and V T and V P and n V and n Is there anyone who can help me with this one? I keep getting it wrong :(

The answer is: P and T - directly proportional P and V - inversely proportional T and V - directly proportional P and n - directly proportional V and n - indirectly proportional The ideal gas law can be presented as: PV = nRT where P - pressure of the gas, V - volume of the gas, n - amount of substance of gas, R - gas constant, T - temperature of the gas. If both members of a pair are on the same side of the equation, they are inversely proportional. If two members of the pair are on opposite side of the equation, they are directly proportional. For example, P and V are on the same side of the equation, so they are inversely proportional. This means that if P increases, V must decrease and vice versa. P and T are on the opposite sides, so they are directly proportional. This means that if P increases, T must increase, too, and vice versa.
