1. In a Callender's compensated constant pressure air thermometer, the volume of the bulb is 1800cc. when the bulb is kept immersed in a vessel,200 cc of mercury has to be poured out. Calculate the temperature of the vessel.( ans 307 k)
2. The volume of a glass vessel is 1000cc at 20 C. What volume of mercury should be poured into it at this temperature so that the volume of the remainig space does not change with temperature ? Coefficients of cubical expansion of mercury and glass are 1.8 * 10 ^ -4 / c and 9.0 * 10 ^ -6 /c respectively. ( ans 50 cc)
