Question
At 27oC, 1 mol gas is allowed to expand reversibly and adiabatically then the final temperature of the system becomes 100 K. If CV = 2.5 J/ mol k then calculate ᐃE for this ?
Options
A.- 2000 J/mol
B.- 2500 J/mol
C.- 500 J/mol
D.zero
Solution
ᐃE = nCVdT
= 1 × 2.5 (100 - 300)
= - 500 J/mol
= 1 × 2.5 (100 - 300)
= - 500 J/mol
