2 Equal volumes of water (density 1 g/cm3) and alcohol (density 08 g/m3)
when put in similar calorimeters take 100 seconds and 74 seconds respectively to
cool from 50° Cto 40° Ccalculate the specific heat of alcohol, Thermal capacity
of each calorimeter is numerically equal to the volume of either liquid.

In similar calorimeters, equal volume of water and alcohol, when poured take 100 s and 74 s respectivel to cool from `50^(@)`C to `40^(@)`C. If the thermal capacity of each calorimeter is numerically equal to volume of either liquid, then calculatethe specific heat capacity of alcohol. <br> (Given, the relative density of alcohol as 0.8 and specific heat capacity of water as 1 `cal/g/^(@)C)`

In Newton's experiment of cooling, the water equivalent of two similar calorimeters is 10 gm each. They are filled with 350 gm of water and 300 gm of a liquid (equal volumes) separately. The time taken by water and liquid to cool from `70^(@)C` to `60^(@)C` is 3 min and 95 sec respectively. The specific heat of the liquid will b
