The temperature of an object is 50F. Find its temperature in C, K, R. O 50C, 213.15K, 500R O 10C, 283.15K, 510R O 50C, 283.15K, 510R O 10C, 213.15K, 500R Question 2 A surveyor uses a steel measuring tape that is exactly 50.000 m long at a temperature of 20C. The markings on the tape are calibrated for this temperature. When it is 35C, the surveyor uses the tape to measure a distance. The value that she reads off the tape is 35.794 at. What is the actual distance? The coefcient of linear expansion of the glass is 1.20 x 10'5 K" o 35.8 m 0 33.5 m C) 39.8 m 0 30.8 m A glass contains 0.25 kg of Omni-Cola (mostly water) initially at 25C. How much ice, initially at -20 C must you add to obtain a final temperature of O'C with all the ice melted? Neglect the heat capacity of the glass. O 0.05 kg O 0.17 kg O 0.15 kg O 0.07 kg Question 7 How much heat is given up when 20g of steam at 100 C is condensed and cooled to 20 C? O 1.6 kcal O 10.8 kcal O 12.4 kcal O 21.6 kcalA piston cylinder device contains a liquid-vapor mixture of water at 500K. During a constant pressure process, 700 KJ of heat is transferred to the water. As a result, part of the liquid in the cylinder vaporizes. Determine the entropy change of the water during this process O 2.4 KJ/K O 1.4 KJ/K O 0.7 K/kg O 5.4 K/kg Question 19 In the process where the product of pressure and the volume is constant, a gas compression is carried out from an intial pressure of 200 kPa to a final pressure of 800 kPa. Consisting that the initial specific volume is 0.10 m3/kg, determine the work done per kilogram of gas. O -32.5 kJ/kg O -27.7 kJ/kg O -41.51 kJ/kg O -52.5 kJ/kg
