Okai so for the first one 
There is no change of temperature mentioned, thus we consider the temperature to be constant. 
Therefore PV= constant. 
P1V1 = P2V2 
So use that and take the answer !

rushwr · Answer

For the second one 
V1/T1 = V2/T2 
Because pressure is constant !

rushwr · Answer

Third one the volume is kept constant , therefore 
P1/T1 = P2/T2

rushwr · Answer

4th one use the combines gas law !  ( as they have given

rushwr · Answer

5th one 
PV = nRT
P pressure pascals
V volume in Litres
R universal gas constant
T temperature in Kelvin ! Now substitute the values and get the answer !
