A flask having a volume of 250.0 mL and ...

A flask having a volume of 250.0 mL and containing air is heated to `100^(@)C` and sealed. Then the flask is cooled to `25^(@)C`, immersed in water, and opened. What volume of water will be drawn back into the flask, assuming the pressure remaining constant ?

Text Solution

Verified by Experts

Volume occupied by air `=(250xx298)/(373)=199.73cm^(3)`
Water drawn back `=250-199.73=50.27cm^(3)`
