Keeping the volume constant, the pressure of the gas is increased by 10% of its original value by increasing the temperature from 27^(0) C. Find the final temperature.

Answer»

Solution :Initial PRESSURE of the gas `(P_(1)) = P `
Final pressure of the gas `(P_(2)) = (110)/(100)` P
Initial temperature `t_(1)^(0) C = 27^(0)` C
`T_(1) = 27 + 273 = 300` K
Final temperature `t_(2)^(0) C `= ?
At constant volume, according to Charles law `(P_(1))/(T_(1)) = (P_(2))/(T_(2))`
`T_(2) = (P_(2))/(P_(1)) T_(1) = (110P//100)/(P) XX 300 = 330`
`t_(2) = 330 - 273 = 57^(0)` C
