4g of he gas is expanded isothermally at 300K from litre to 10L. The molar change in entropy is:

If one mole of an ideal gas (C_(p.m.)=(5)/(2)R) is expanded isothermally at 300K until it’s volume is tripled, then change in entropy of gas is:

If one mole of an ideal gas (C_(p.m.)=(5)/(2)R) is expanded isothermally at 300K until it’s volume is tripled, then change in entropy of gas is:

If one mole of an ideal gas (C_(p.m.)=(5)/(2)R) is expanded isothermally at 300K until it’s volume is tripled, then change in entropy of gas is:

One mole of an ideal gas expands isothermally at 300 K from 1 litre to 101 litres at constant pressure of 1 atmosphere. The work done during this change is (1 lit atrn = 24.2 cals)
