Question Number 15019 by tawa tawa last updated on 06/Jun/17
1.00 Mol of a monoatomic gas initially at 3.00 × 10^2 K and occupying    2.00 × 10^(−3 ) m^3  is heated to 3.25 × 10^2 K and the final volume is 4.00 × 10^(−3) m^3 .   Assuming ideal behaviour , Calculate the entropy change for the system.
