Question
An amount Q of heat is added to a monoatomic ideal gas in thermodynamic process. In the process gas expands and does Q/2 Work. Molar specific heat of the gas is :-
Options
A.R
B.2R
C.3R
D.4R
Solution
Q = W + ᐃU; Q = 
+ ᐃU
∴ ᐃU =
nCv ᐃT =
nCᐃT
∴ C = 2Cv = 2 ×
= 
+ ᐃU∴ ᐃU =
nCv ᐃT =
nCᐃT∴ C = 2Cv = 2 ×
