If one mole of an ideal gas `C_p = 5/2 R` is expanded isothermally at 300 k until it's volume is tripled., if expansion is carried out freely `(P_(ext)=0), then DeltaS is :`
A
zero
B
infinity
C
`R ln 3`
D
None
Text Solution
Verified by Experts
The correct Answer is:
C
`DeltaS` will be same because entropy is a state function.

One mole of ideal gas expands isothermally to double its volume at 27^(@)C . Then the work done by the gas is nearly
Two mole of an ideal gas is expanded irreversibly and isothermally at 37^(@)C until its volume is doubled and 3.41 kJ heat is absorbed from surroundings. Delta S_("total") (system + surroundings) is
Two litres of an ideal gas at a pressure of 10 atm expands isothermally into a vacuum until its total volume is 20 litres. How much heat is absorbed and how much work is done in the expansion?
0.14kg of nitrogen at 300K is expanded isothermally and reversibly until its volume becomes doubled. Calculate the work done by the gas.
One mole of an ideal gas at 300K is expanded isothermally reversibly from an initial volume of 1 litre to 10 litres. The Delta E for this process is (R = 2 cal mol^(-1) K^(-1) )
