Question

2 liters of a gas is enclosed in a vessel when pressure is 760mm. If the temperature remains constant calculate the pressure when:

a. volume changes to 4 dm3 4dm=4l
b. The volume is increased by one and half times

Answer 1

Answer:

4 decimeter cube equal to 4 litre

PV = n RT

at constant temperature PV is constant

that is P is inversely proportional to V

as volume Doubles pressure reduced to half

i.e P final = 380 mm of Hg.
