Question

How will pressure change if volume is made half of its original value keeping the temperature constant?

Answer 1

u should refer the Boyles law .... according to Boyles law...pressure of an ideal gas is inversely proportional to its volume.....

so....P1V1 = P2V2....

but it is given that final volume is half of its initial one.....so.....

V1 = 2 V1

so.....P1 (2V2) = P2V2

2P1 = P2

hence ....P2 = 2P1


i.e. final pressure = 2 × initial pressure

Answer 2

pressure will be doubled
