Question

The pressure of a gas at STP is doubled and the temperature is raised to 546K.
Calculate the final volume of the gas.

Answer 1

Answer:

Pv=nRT

2PV=nR (2T)

2/2 =1 so volume remains same

remember in gas laws when two things are changing all other quantities remain constant !

P is directly proportional to temp ( gay lussacs law ) so volume remains constant .

But if temperature becomes half and pressure becomes double our volume does not remains constant but But decreases by four
