Heat and Thermal ExpansionHard
Question
In a mercy = glass thermometer the cross - section of the capillary portion is A0 and the volume of the bulb is V0 at 273 K. If and are the coefficients of linear and cubical expansion coefficients of glass and nerdy respectively then length of mercury in the capillary at temperature toC is (ignore the increases in cross- sectional area of capillary)
