-18% 20C quart container of vanilla ice cream with chocolate chips has been left out on the kitchen counter by accident, where Sam ed it to soften, and then completely forgot about it. (Sam left another pint in the freezer.) The ice cream that began as 18 C in the freezer has now has warmed up to 20C. Since this brand has a melting point of -4 C, it has entirely liquified. The quart container is cylindrical with radius 6 cm and height of 8.4 cm. The pint container is also a cylinder with radius 5 cm and height 6 cm, but half the mass of the quart. The bottom of these containers is completely flat, not with a small ridge around the edge. The density of the ice cream is 568 kg/m so that a quart has a mass of 536 grams. The specific heat of ice cream when melted is 2.9 J/kg-K. When frozen the specific heat is 1.6 J/kg-K. The ice cream heat of fusion is 210 J/kg. BA B 14. In melting the ice cream, where did most of the heat go? (A) Raising the temperature of frozen ice cream from -18C to -4 C. (B) Melting the ice cream once it got to -4C (C) Raising the temperature from -4 to 20. (D) You can't tell. the mass 15 If instead Sam had left the pint out, (A) it would have absorbed heat faster than the quart container (B) it would have absorbed heat slower than the quart container (C) it would have absorbed heat at the same rate as the quart container. B B 16. Comparing the full pint container to the full quart container, (A) the pint exerts more pressure on the table (B) 3 C the pint exerts less pressure than the quart container (C) the pint exerts the same pressure as the quart container. 17. To this 17. To compute the buoyant force on a specific chocolate chip in this melted ice cream you need to use (A) the density of water (B) the density of chocolate chips (C) the density of the ice cream (D) more than one of the above. D 18. If the pint had melted instead of the quart, how would the pressure inside the container at the bottom have compared? (A) The pressure in the quart would be 2 times the pint. (B) The pressure in the quart would be 6/5 times the in the pint. (C) The pressure in the quart would be (6/5) times the pressure in the pint. (D) The pressure in the quart pressure in the pint. would be 8.4/6 times the pressure in the pint. SHOW ALL WORK IN THE SPACE BELOW. NO CREDIT FOR AN ANSWER THAT IS NOT CLEARLY EXPLAINED. 19. How large was the entropy change when it melted? NO
