Answer to this 2 questions please!

so that brings the gas to 550 K and 1.5 atm? 14. INT . . A system consists of a 1.0 kg block of copper at 20.C and 1.5 kg block of copper at 300.C. The two blocks, isolated from the environment, are placed in contact until thermal equilibrium is reached. What is the change in entropy of the system? The specific heat of copper is 385 J/kg . K. 15. . . A container is divided into two equal volumes by a very thin membrane. It is held at a fixed temperature by immersion in a water bath. The left half holds 1.0 mol of gas, and the right half holds 2.0 mol of the same gas. The membrane is then punctured so that gas can flow freely between the two sides. What is the change in the entropy of the system after the gas has come to equilibrium
