In this question information is not given by its temperature. 
So here i am assuming there is no change in temperature.
If Temperature is constant than apppying Boyle's law-
                   P alpha 1 over V P subscript 1 over P subscript 2 equals V subscript 2 over V subscript 1 P subscript 1 equals P comma space P subscript 2 equals P plus P cross times 20 over 100 equals P plus.2 P equals 1.2 P V subscript 1 equals 2 cross times 10 to the power of negative 3 end exponent space m cubed V subscript 2 space end subscript equals space ? fraction numerator P over denominator 1.2 P end fraction equals fraction numerator V subscript 2 over denominator 2 cross times 10 to the power of negative 3 end exponent end fraction V subscript 2 equals 1.6 cross times 10 to the power of negative 3 end exponent space m cubed space space space space space equals 1.6 space d m cubed
