Document Summary
Multiple-choice questions (56 points; 8 points per question). G. 0. 524t: a substance has a melting point of 20 c and a heat of fusion of 3. 5 104 j/kg. The boiling point is 150 c and the heat of vaporization is 7. 0 104 j/kg at a pressure of 1. 0 atm. The specific heats for the solid, liquid, and gaseous phases are 600 j/(kg k), 1000 j/(kg k), and 400 j/(kg k), respectively. The quantity of heat given up by 0. 50 kg of the substance when it is cooled from 170 c to 88 c, at a pressure of 1. 0 atmosphere, is closest to. 140 kj. (multiple-choice questions continue on the next page) Physics 2 second midterm 5/23/2013 11 am lecture: a lightly damped harmonic oscillator, with a damping force proportional to its speed, is oscillating with an amplitude of 0. 500 cm at time t = 0. When t = 8. 20 s, the amplitude has died down to 0. 400 cm.
