Unformatted text preview: Version PREVIEW HW 7 Savrasov (39824) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. Holt SF 10Rev 45 001 10.0 points At what Fahrenheit temperature are the Cel- sius and Fahrenheit temperatures numerically equal? Correct answer:- 40 F. Explanation: Basic Concept: T F = 9 5 T C + 32 Solution: x = 9 5 x + 32- 4 5 x = 32- 5 4 parenleftbigg- 4 5 parenrightbigg x =- 5 4 (32) x =- 40 Thus- 40 C =- 40 F. Tipler PSE5 17 31 002 (part 1 of 2) 10.0 points The length of the column of mercury in a thermometer is 3 . 5 cm when the thermometer is immersed in ice water and 25 . 5 cm when the thermometer is immersed in boiled water. What should be the length at room tem- perature, 22 C? Correct answer: 8 . 34 cm. Explanation: Let : L = 3 . 5 cm and L 100 = 25 . 5 cm . 100 C L 100 C L T L Set up a proportion with the calibration temperatures and heights: T- C 100 C- C = L- L L 100- L 100 C ( L- L ) = T ( L 100- L ) L = T ( L 100- L ) 100 C + L = (22 C) (25 . 5 cm- 3 . 5 cm) 100 C + 3 . 5 cm = 8 . 34 cm . 003 (part 2 of 2) 10.0 points If the mercury column is 27 . 4 cm long when the thermometer is immersed in a chemical solution, what is the temperature of the solu- tion?...
