2)'if pressure is decreases , volume is increases and if pressure increases, volume decreases.

3) term is used- inversely proportional

4) Charles law,.

T/V = constant (at constant pressure)

5) Gaylussac's law,

P1/T1 = P2/T2

T2 = P2×T1/P1

6) combined gas law,

PV = nRT

So , P1V1/T1 = P1V2/T2
