Question

A gas is contained in a vessel of capacity 10 litres at a pressure of 20 atm. When this container is
connected to another empty container of the same capacity, find the new pressure of the gas. Assume
the temperature to be constant.
(Ans. 10 atm)​

Answer 1

Answer:

10 atm

Explanation:

According to Boyle's law P1V1 =P2V2

Here P1 = 20 atm

V1 = 10 atm

P2 = ?

V2 =10L + 10L (because both the containers are connected)

Therefore P1V1 =P2V2

ie, (20×10)÷ V2 =P2

ie, 200÷20 =10atm
