When a block of metal of specific heat `0.1 cal//g//^@C` and weighing 110 g is heated to `100^@C` and then quickly transferred to a calorimeter containing `200g` of a liquid at `10^@C`, the resulting temperature is `18^@C`. On repeating the experiment with 400 g of same liquid in the same calorimeter at same initial temperature, the resulting temperature is `14.5^@C`. find
a. Specific heat of the liquid.
b. The water equivalent of calorimeter.

Answer

`S_(L)=0.481"cal"g^(-1).^(@)C^(-1);W_(C)=16.55g`
