Question

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 cm 3 of water at 27°C. The final temperature is 40°C. The specific heat of the metal is -, 0.1 cal g –1 °C –1, 0.2 cal g –1 °C –1, 0.3 cal g –1 °C –1, 0.4 cal g –1 °C –1

MARKS App · Accepted Answer

Heat lost by the metal = Heat gain by water + calorimeter 0.20 × 1 0 3 × c × 1 5 0 - 4 0 = 175 × 13 c = 175 × 13 110 × 200 ≈ 0 . 1 cal g - 1 ° C - 1
