MULTIPLE CHOICE (1 points each; circle one of 1. Each morning, you step barefoot onto the bathroom floor. You put one foot on the tile, and one foot on the rug. The tile feels cooler than the rug. Why? (a) The tile is actually colder (lower temperature) than the rug (b) The rug is a better conductor, conducts more heat to your feet c) The tile is a better conductor, conducts heat away from your foot more quickly (d) The tile and rug are both equally conductive; the tile has a greater emissivity, e 2. The James Webb Space Telescope is in deep space, in orbit around the Sun on the far side of the Moon. The telescope is shielded from the Sun by a huge heat shield. The sunny side of heat shield (facing the Sun) reaches a max temperature of 382.9 K (109.9 .C). The shady side of the heat shield (facing away from the Sun) reaches a minimum temperature of 36 K (-237 .C). What is that temperature of the sunny side of heat shield, in degrees Fahrenheit? (a) -394.9 OF (b) 29.1 OF (c) 165.8 OF (d) 230 F 483 KD 3. Prof. Conlin is playing with a simulation of a sealed can of ideal gas. He removes heat by putting ICE under the can of gas at constant volume. What happens to the temperature T and pressure P of the gas? (a) Both Pressure P and temperature T INCREASE (b) Pressure P increases; Temperature T stays constant (c) Pressure P stays constant; Temperature T increases (d) Pressure P decreases; Temperature T increases (e) Both Pressure P and temperature T DECREASE
