D Question 1 1 pts A solid block of a certain material has a volume Vo at 20C. The volume of the block increases by 0.896% when the temperature increases to Ty. The coefficient of volume expansion is B = 168.641/ . Determine the final temperature If (in C). D Question 2 1 pts A closed container has a n moles of an ideal mon-atomic gas at an initial temperature of -74.6 C' and a pressure of 0.847atm and a volume of 57.4cm the pressure and volume are increased to 3.288atm and 189.3cm . Determine the final temperature of the gas (in ' C'). D Question 3 1 pts A block of copper, 77.4g is initially at 216 C. The copper block is placed in a small contianer of water at 28.3 C. The mass of the water is 316g. The specific heat of water is 41864 kgc . The specific heat of copper is $854 Ko The latent heat of fussion for water is Ly = 334. Assume the container is a perfect insulator and does not significantly affect the final temperature of the water- copper block system. Determine the final temperature of this system (in . C)?Question 4 1 pts A metal sphere of radius 7.70m is at a temperature of 307 C. The sphere is in a container that is held at a temperature of -85 C. The speher has an emissivity of 6 20.712. Determine the net rate of energy being radiated from the sphere (in PM. (The stephan-Boltzmann Constant is or = 56.771, :24 ,the n is nano) m Question 5 1 pts A manufacturer claims that a real heat engine can operate between two temperatures. TH =683 C and TC 214000 , and, the engine is able to take 95kJ from the hot side, do some work and then reject 45kJ to the cold side. Determine the amount of work done by a Carnot engine operating between the same two temperatures and taking 95kJ from the hot side (in kJ). Question 6 1 pts A trench in the Pacic Ocean is 55m deep. Assuming that sea water has an average density of 1040kg/m3, calculate the absolute (total) pressure at the bottom of the trench in atmospheres
