Indicate whether the statement is true or false.A liquid has a constant CP=100 J/mol•K. 1 mole of this liquid is confined in a piston-cylinder device, with an initial temperature of T=500 K and pressure P=1 bar. The insulation is removed from the cylinder, allowing it to exchange heat with the surroundings, which can be modeled as a heat reservoir at T=300 K and P=1 bar. The process continues until the liquid in the cylinder reaches equilibrium with the surroundings.
A) Find the change in entropy of the liquid resulting from this process. B) Find the change in entropy of the universe resulting from this process.
