Choose the one alternative that best completes the statement or answers the question. 1) The coefficient of volume expansion of olive oil is 0.68. 10- 3 x-t. A f-Iiter glass beaker is filled to the brim with olive oil at room temperature. The beaker is placed on a range and the temperature of the oil and beaker increases by 25 CO. As a result, 0.0167 liters of olive oil spill over the top of the beaker. What is the coefficient of linear expansion of glass? A) 2 10- 5 K-l ~ '10-5K-l ) x 10-6 x-t t , 10-6 x-i E) 1 10-5 K-l 2) Water at room temperature of 20.0'C is poured into an aluminum cylinder which has graduation markings etched on the inside. The reading in the graduations is 300.0 cc. The cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100'C. What is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? The volume coefficient of expansion of water is 2.07 10- 4 K-l, and the linear coefficient of expansion of aluminum~ 10- 6 x-t. A) 305.0 cc B) 304.0 cc C) 303.5 cc V 0 3 . 3 cc E) 304.5 cc 3) What would be the greatest effect of the finite size of molecules on the ideal gas law? A) At low densities, the pressure would be higher. than that predicted by the ideal gas law. B) At high densities, the pressure would be less than that predicted by the ideal gas law. (2 " At low densities, the pressure would be less than that predicted by the ideal gas law. D At high densities, the pressure would be greater than that predicted by the ideal gas law. ) There is no effect 4) It is a well-known fact that water has a higher specific heat capacity than iron. Now, consider equal masses of water and iron that are initially in thermal equilibrium. The same amount of heat, ~ ries, is added to each. Which statement is true? A ey are no longer in thermal equilibrium; the iron is warmer. ) They are no longer in thermal equilibrium; the water is warmer. C) They remain in thermal equilibrium. 0 ) It is impossible to say without knowing the exact mass involved. E) It is impossible to say without knowing the exact specific heat capacities. G) system consists of two therrnal reservoirs in contact with each other, one at temperature 300'C and the other at temperature 200'C. 600 I of heat transfers from the 300'C reservoir to the 200'C reservoir. What is the change in entropy of this system? U A)1.00 JIK B) 2.31 JIK C) -1.00 JIK D) 0.221 IlK ~.OO JIK He't~-\;- tf'ON~t-eV 1 I) L 2) .D 3) D 4)-fL E 5) @y...
