A gas is filled in a vessel at a certain temperature and pressure. At the same temperature more gas is filled in the vessel so that its mass increases by 40%. Calculate the ratio of initial and finial pressures.

Text Solution

Verified by Experts

The correct Answer is:
At constant temperature `overline(V^(2))` is constant.
Hence, `P propM`
`5:7`
