What volume of air will be expelled from...

What volume of air will be expelled from a vessel containing `400 cm^(3)` at `7^(@)C` when it is heated to `27^(@)C` at the same pressure?

Text Solution

Verified by Experts

`(V_(1))/(T_(1))=(V_(2))/(T_(2))`,
i.e., `(400 cm^(3))/((273+7)K)=(V_(2))/((273+27)K)`
or `V_(2)=(400)/(280)xx300 cm^(3)=482.6 cm^(3)`
This is the volume after expansion. So
Volume expelled `=(428.6-400)cm^(3)=28.6 cm^(3)`
