Question

A copper pot with a mass of 0.475 kg contains 0.150 kg of water, and both are at a temperature of 20.0°C. A 0.235 kg block of

Answer 1

Answer #1

using principle of calorimetry

heat gained by copper pot = heat released by iron block

0.15* 4186* ( T - 20) + 0.475* 390* ( T - 20)= 0.235* 470* (84.5 - T)

(T - 20) ( 813.15) = 9333.025 - 110.45 T

T = 27.71 C
