At `27^(@)C`, a certain mass of gas exerts a pressure of 6 cm of Hg column. What will be the pressure (in cm of Hg) exerted when it is heated to `127^(@)C` at constant volume ?

Text Solution

Verified by Experts

The correct Answer is:
8
Here, `T_(1)=27+273=300K`
`P_(1)=6cm` of Hg col.
`T_(2)=127+273 = 400K, P_(2)=?`
as the gas is heated at constant volume,
`(P_2)/(P_1) =(T_2)/(T_1) , P_(2) = P_(1)xx(T_2)/(T_1)`
`=6xx400/300 = 8cm` of Hg col.
