The steam point and the ice point of a Mercury thermometer are marked as 80^0 and 20^0 . What will be the temperature in centigrade mercury scale when this thermometer reads 32^0 ?

A platinum resistance thermometer is constructed which reads ,0^0 at ice point and 100^0 at steam point. Let t_p denote temperature on this scale and let t denote the temperature on a mercury on a mercury thermometer scale. The resistance of the platinum coil varies with t as R_1 = R_0 (1+alphat + betat^2) . Derive an expression for the resistance as a function of T_p .

The length of the mercury column in a mercury thermometer was 15mm when it was placed in melting ice, 200mm when it was placed in steam and 100mm when it was placed in a hot liquid. What is the temperature of the liquid?

Explain the construction and working of Westron standard cell.

Explain the construction and working of an astronomical telescope. Calculate its magnifying power when the image is formed at the least distance of distinct vision.

Name the principle used in the mercury thermometer.

The coefficient of linear expansion of glass is alpha_g per .^(@)C and the cubical expansion of mercury is gamma_m per .^(@)C . The volume of the bulb of a mercury thermometer at 0^@C is V_0 and cross section of the capillary is A_0 . What is the length of mercury column in capillary at T^@C , if the mercury just fills the bulb at 0^@C ?
