A direct relationship is when both variables faces a change in the similar direction. An inverse relationship is when both variables faces change in different directions.

Lusaac's law applies to gas help at a constant volume allowing only the pressure and temperature to vary.

Therefore, Lussac's Law involves pressure and temperature. It's an direct relationship since as pressure increases, temperature increases as well.

The formula for Lusaac's law is P1/T1 = P2/T2

P1 - Initial Pressure

T1 - Initial Temperature

P2 - Final Pressure

T2 - Final Temperature
