A solids floats submerged in a liquid. when the liquid is heated
Equal volumes of water and alcohol when put in similar calorimeters take 100 sec and 74 sec respecively to cool from 50∘C to 40∘C. The thermal capacity of each calorimeter in numerically equal to the volume of either liquid. The specific gravity of alcohol is 0.8 if the specific heat capacity of water is 1 cal/gm, the specific heat capcity of alcohol will

A steel scale measures the length of a copper wire as 80.0 cm when both area at 20∘C (the calibration temperature for scale). What would be the scale read for the length of the wire when both are at 40∘C? (Given α steel = 11×10^−6 per∘C and α copper= 17 × 10^−6 per∘C)

A glass flask of volume one litre at 0∘C is filled, level full of mercury at this temperature. The flask and mercury are now heated to 100∘C. How much mercury will spill out if coefficient of volume expansion of mercury is 1.82 × 10^−4/∘C and linear expansion of glass is 0.1 × 10^−4/∘C respectively?

Two wires A and B of the same cross sectional areas. Young’s moduli Y1 and Y2 and coefficients of linear expansion α1 and α2 respectively are joined together and fixed between rigid supports at either ends. The tension in the compound wire when wire A is heated and wire B is cooled at different temperature is same when wire A alone is cooled at the same temperature as wire B earlier. Find correct oprtion.
