A quantity of 6.0 moles of an ideal gas is reversibly heated atconstant volume from 17 degrees Celsius to 35 degrees Celsius.Calculate the entropy change. What would be the value of delta S if the heating were carried out irreversibly?
Homework Answers
In this question calculated the entropy by using constant volume and taking two temperature and mole
When the process is constant volume is called isochoric process
So apply the formula and calucated the value of entropy
And one thing cv is 3/2 R and 3/2R is translation motion only so we use 3/2R....
