Psychologist joanne wood and her colleagues recruited people with high and low self-esteem to participate in a study of positive self-statements (wood, perunovic, & lee, 2009). they asked participants to write their thoughts and feelings down for 4 minutes. they randomly assigned half the participants to repeat to themselves a positive self-statement, "i am a lovable person", at 15-second intervals (cued by a bell sound). the other half did not repeat this phrase. after the 4-minute session, all participants rated their mood on a subtle mood questionnaire. here are the results: [see table above]

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 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc
