A gas expands from 3 dm3 to 21 dm3 against a constant pressure of 2.1 – InterviewSolution

1.	A gas expands from 3 dm3 to 21 dm3 against a constant pressure of 2.1 atm. The work during expansion is used to heat 10 mole of water of temperature 290 K. Final temperature of water (in K)is: (Round the answer to the nearest intiger.)(Given: Specific heat of water=4.2 J g−1 K−1, 1 L.atm=101.325 J)
Answer» A gas expands from $3 d m^{3}$ to $21 d m^{3}$ against a constant pressure of $2.1 a t m .$ The work during expansion is used to heat $10$ mole of water of temperature $290 K .$ Final temperature of water $(i n K)$ is: (Round the answer to the nearest intiger.) $(Given: Specific heat of water = 4.2 J g^{- 1} K^{- 1}, 1 L . a t m = 101.325 J)$
