In an experiment of measuring specific heat of a liquid, a stream of liquid flows at a steady rate of `5 g / s` over an electrical beater dissipating `135 W` and a temperature rise of `5 K` is observed. On increasing the rate of flow to `10 g / s`, the same temperature rise is produced with `(a)` dissipation of `235 W`. Find the specific heat `J g^(-1) K^(-1))` of the liquid. (Assume heat loss to the surrounding in both the cases is same.)
