Isabelle pour 158cm3 of glycerin, at a temperature of -12 oC, into a graduated cylinder initially at 19 oC, filling it to the very top. The cylinder is made of glass with a specific heat of 840 J/kg-K and a coefficient of volume expansion of 1.2 x10−5K-1 ; its mass is 0.110kg. The mass of the glycerin is 0.0873 kg. (a) What will be the final temperature of the glycerin, once thermal equilibrium is reached? (b) How much glycerin will overflow the cylinder before thermal equilibrium is reached?

Cold salt brine at -2°C is used in a packing plant to chill food slabs from 40°C to 3.4°C in 18 hours. Determine the mass of brine required to cool 100 food slabs of 225 kg each if the final temperature of the brine is 1.7°C.
A cylinder is fitted with a freely movable piston of area 1.20e-2m^2 and negligible mass. The cylinder below the piston is filled with a gas. At state 1 the gas has volume 1.50e-3m^3, pressure 1.02e5Pa, and the cylinder is in contact with a water bath at a temperature of 0.0C. The gas is then taken through the following four step process. - A 2.50kg metal block is placed on top of the piston, compressing the gas to state 2, with the gas still at 0.0 C. - The cylinder is then brought in contact with a boiling water bath, raising the gas temperature to 100C at state 3. - The metal block is removed and the gas expands to state 4 still at 100C. - Finally, the cylinder is again placed in contact with the water bath at 0C, returning the system to state 1. a) Determine the pressure of the gas in state 2. b) Determine the volume of the gas in state 2. C) Determine the volume of the gas in state 4. Answer all parts, ABC
Many gyms and health clubs have steam saunas, which are small steam-filled rooms. Traditionally, steam saunas have a container of heated rocks. A small ladle of water is poured on the rocks in order to make the steam. Use what you have learned so far about heat transfer to explain how hot rocks can be used to make steam? Why do you think only a small ladle-full of water is poured on the rocks at one time?
3.0 kg of steam at a pressure of 100 kPa are contained in a rigid sealed tank of volume 5.95 m3. The steam begins to cool as heat is transferred to the atmosphere.
