Part A: Multiple Choice: Choose the most appropriate answer among those suggested and place its letter in the blank to the left of it. Which one of the following statements is true? Temperatures differing by 25 degree on the Fahrenheit scale must differ by 45 degree on the Celsius scale 40 K corresponds to 40 degree C Temperatures which differ by 10 degree on the Celsius scale must differ by 18 degree on the Kelvin scale Water at 90 degree C is warmer than water at 202 degree F 32 degree F corresponds to 0 degree C The approximate number of air molecules in a I m3 volume of an ideal gas at room temperature (300 K) and pressure of 2 atm is: (Use R = 8.2 times 10-5(m3 . atm)/(mol .k)) 5.0 times 1030 5.4 times 1026 4.9 times 1025 8.2 times 106 81 The coefficient of linear expansion of steel is 11 times 10-6 1/C degree. A steel ball has a volume of exactly 50 cm3 at 0 degree C. When heated to 100 degree C, its volume becomes: 50.165 cm3 50.055 cm3 50.000011cm3 50.000033cm3 none of these
