In an experiment on the specific heat of a metal, a 0.20 kg block of the metal at 150°C is dropped in a copper calorimeter (of water equivalent 0.025 kg) containing 150 cm³of water at 27°C. The final temperature is 40°C. The specific heat of the metal is -

Options:

Answer:

Solution:

Heat lost by the metal = Heat gain by water + calorimeter

$0.20 \times 1 0^{3} \times c \times (150 - 40) = 175 \times 13$

$c = \frac{175 \times 13}{110 \times 200} \approx 0.1 cal g^{- 1} ° C^{- 1}$
