A mas of air is saturated with water vapour at `100^(@)C`. Onl raising the temperature to `200^(@)C` without change of volume, the mixture exerts a pressure of `2xx10^(5)` pascals (Pa). What was the pressure of air alone in the ilnitial conditions? (Saturated vapour pressure of water at `100^(@)C=10^(5)Pa`)
Text Solution
Verified by Experts
The correct Answer is:
`1.54xx10^(5)Pa`
