662 APPLIED SCIENCES weight thermometer is found to contain 200 grammes of mercury at it is then lowered into vessel of water and after removal is found to contain 1996 grammes of mercury determine the temperature of the water assuming that the co-efficient of apparent expansion of mercury 6480' Explain clearly the apparatus and mode of experimenting necessary for determining the co-efficient of expansion of air under constant pressure under constant volume thousand cubic inches of air under pressure of 10136 lbs per square inch are allowed to expand till the pressure becomes 10 lbs per square inch and the temperature is at the same time raised from to 100 Find the final volume י י י י Give an account of Regnaultfs experiments on the tension of aqueous vapour at different temperatures Describe fully Regnault's apparatus for determining the specific heat of solid substances If solid weighing Ρ grammes be heated to temperature and then plunged into grammes of water at temperature find the rise of temperature assuming that the specific heat of the Rubetance SECOND AND THIRD YEARS Two weights are carried on pole which rests at and iV on the shoulders of two men one weight is 40 lbs and is put at point such that MC is to CN as is to the other weight is 56 lbs and is put at point such that MD is to DN as is to find the weight which each man must bear Two uniform cylinders of 72 and specific gravity respectively are joined end to end so that their axes are in the same straight line one cylinder is inches long and finches in diameter and the other is inches long and
