Problems 8.1 Convert the following temperatures to Fahrenheit: 115°C, 456 K, and 423°R. 8.2 Convert the following temperatures to Rankine: -13°C, 645 K, and -123°F. 8.3 Convert the following temperatures to Centigrade: 115°F, 356 K, and 533°R. 8.4 Convert the following temperatures to Kelvin: -215°C, -56°F, and 436°R. 8.5 How many calories of energy are required to raise the temperature of 3 ft of water 15°F? 8.6 A 15-lb block of brass with a specific heat of 0.089 is heated to 189°F and then immersed in 5 gal of water at 66°F. What is the final temperature of the brass and water? Assume there is no heat loss. 8.7 A 4.3-lb copper block is heated by passing a direct current through it. If the voltage across the copper is 50 V and the current is 13.5 A, what will be the increase in the temperature of the copper after 17 min? Assume there is no heat loss.
