The pressure of a gas kept in an isothermal container is `200Kpa`. If half the gas is removed from it, the pressure will be

A

100 kPa

B

200 kPa

C

400 kPa

D

800 kPa

Text Solution

Verified by Experts

The correct Answer is:
A
for isothermal process, temperature remains constant According to ideal gas equation,
`pV=nRT`
For a given container ,V remains constant.
`therefore` " " p`prop`n
When half of gas is removed, number of moles becomes half.Hence, p[ressure becomes half.
