A 100-lbm block of a solid material whose specific heat is 0.5 Btu/lbmR is at 80∘  ∘  F. It is heated with 10 lbm of saturated water vapor that has a constant pressure of 20 psia. Determine the final temperature of the block and water, and the entropy change of (a) the block, (b) the water, and (c) the entire system. Is this process possible? Why?

What is the decrease in entropy of 44.8 g of water that condenses on a bathroom mirror at a temperature of 39.7°C, assuming no change in temperature and given the latent heat of vaporization to be 2450 kJ/kg? Select the correct answer O 396 J/K O 189 J/K X Your Answer O 209 J/K 351 J/K O 251 J/K

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?

How much energy must be transferred as heat for a reversible isothermal expansion of an ideal gas at 132°C if the entropy of the gas increases by 46.0 K

A block made of cobalt with a mass of 0.80 kg is heated to 850°C, then dropped into 5.00 kg of water at 10°C. What is the total change in entropy (in J/K) of the block-water system, assuming no energy is lost by heat from this system to the surroundings? The specific heat of cobalt is 420 J/(kg · K), and the specific heat of water is 4,186 J/(kg · K). (Hint: note that dQ = mcdT.)

What is the decrease in entropy (in J/K) of 30.0 g of water that condenses on a bathroom mirror at a temperature of 33.5°C, assuming no change in temperature and given the latent heat of vaporization to be 2450 kJ/kg?

A 100-lbm block of a solid material whose specific heat is 0.5 Btu/lbm·R is at 80°F. It is heated with 10 lbm of saturated water vapor that has a constant pressure of 20 psia. Determine the final temperature of the block and water, and the entropy change of the entire system. Is this process possible? Why?
