System A and system B are thermally isolated from everything else but exchange heat with each other. System A is initially at 300 K andsystem B is initially at 400 K. System A has mass 2.0 kg and specific heat 1000 J/kg K. System B has mass 1.0 kg and the same specific heatof 1000 J/ kg K. What is the net (total) change in entropy from the initial state to the final equilibrium state? Hint: you need to determinethe final equilibrium temperature.-1000 J/K+29.4 J/K+26.7 J/K+25.3 J/K-47000 J/KAT₁ = 300KC = 1000J/kg. Km = 2.0 kgBTi = 400KC = 1000J/kg. K1.0 kgm =

A 2.00-L container has a center partition that divides it into two equal parts as shown below. The left side contains n = 0.029 0 mol of H2 gas, and the right side contains n = 0.029 0 mol of 02 gas. Both gases are at room temperature and at atmospheric pressure. The partition is removed, and the gases are allowed to mix. What is the entropy increase of the system? J/K
For ice melting into water at 0 °C, the latent heat of fusion is Lp = 3.34 x 105 J/kg. For water boiling at 100 °C, the latent heat of vaporization is Ly = 2.26 x 105 J/kg. Which process involves a greater change in entropy? O melting 1.00 kg of ice at 0 °C O vaporizing 1.00 kg of liquid water at 100 °C the entropy change is the same for both
*80. D The sun is a sphere with a radius of 6.96 X 10° m and an av- erage surface temperature of 5800 K. Determine the amount by which the sun's thermal radiation increases the entropy of the entire universe each second. Assume that the sun is a perfect blackbody, and that the average temperature of the rest of the universe is 2.73 K. Do not con- sider the thermal radiation absorbed by the sun from the rest of the universe.
A high temperature reservoir losing heat and hence entropy is a reversible process. A low temperature reservoir gaining a certain amount of heat and hence entropy is a reversible process. But a high temperature reservoir losing heat to a low temperature reservoir is irreversible. Why?
A large factory furnace maintained at 170 ∘C at its outer surface is wrapped in an insulating blanket of thermal conductivity 5.50×10−2 W/(m⋅K) which is thick enough that the outer surface of the insulation is at 43.0 ∘C while heat escapes from the furnace at a steady rate of 140 W for each square meter of surface area. By how much does each square meter of the furnace change the entropy of the factory every second?
