Question

Cristina mixed 10kg of water at 70° with 20 kg of water at 20°C,if an equilibrium temperature of 40°C was obtained,find the heat absorbed by the mass of 20kg.A:400 kcalB:300 kcalC:450kcalD:350 kcal

Answer 1

Given:

The mass of the water is m = 20 kg

The initial temperature of water is T1 = 20 deg C

The final temperature of water is T2 = 40 deg C

The specific heat of water is c = .
