A 199 g piece of metal is rapidly removed from a furnace at a temperature of 600 °C and quenched in 1600 g of water. The initial temperature of the water is 20 °C. If the final temperature of both metal and water reach 32 °C and knowing that the specific heat capacity of water is 4190 J kg-1 °C-1, calculate the specific heat capacity of the metal in J kg-¹ °C-1, (to 1 d.p.).

Wheatstone Bridge Method

A Wheatstone bridge is a circuit used to measure unknown resistance by measuring the ratios of the two branches of the circuit such that each branch has two resistance and out of four resistance one is unknown. The two branches are joined in between with the help of galvanometer which is used to determine the direction of the current. The main advantage of this circuit is that it can provide the most accurate measurement (different from a simple voltage separator).
