Question

Initial temperature of an ideal gas is `75^(@)C.` At what temperature, the sample of neon gas would be heated to double its pressure, if the initial volume of gas is reduced by 15%?
A. `319^(@)C`
B. `592^(@)C`
C. `128^(@)C`
D. `60^(@)C`

Answer 1

Correct Answer - A
`P_(1)=P,V_(1)=V,T_(1)=27375=348K`
`P_(2)=2P,V_(2)=(85)/(100)V,T_(2)=?`
`(PxxV)/(348)=(2Pxx85V)/(T_(2)xx100)implies T_(2)=(348xx2xx85)/(100)`
`:. T_(2)= 591.6 K = 318 .6^(@)C`
