A mercury thermometer is constructed as shown if Fig. 1.9. The capillary tube has a diameter of 0.004 00 cm, and the bulb has a diameter of 0.250 cm. neglecting the expansion of the glass, find the change in height of the mercury column with a temperature change of 30.`0^@C`.

Volume of the bulb of a mercury thermometer at 0^(@)C is V_(@) and area of cross section of the capillary tube is A_(0) , coefficient of linear expansion of glass is alpha_(g) , and the cubical expansion of mercury is gamma_(m) . If the mercury fills the bulb at 0^(@)C , find the length of mercury column in thermometer at T^(@)C

In a mercury-glass thermometer the cross-section of the capillary portion is A_(0) and the volume of the bulb is V_(0) at 273K . If alpha and gamma are the coefficients of linear and cubical expansion coefficients of glass and mercury respectively then length of mercury in the capillary at temperature t^(@)C is (Ignore the increase in cross-sectional area of capillary)
