Question

bucket containing 8 kg of water at 20 degree celsius when 4 kg of water is mixed with it the temperature of the mixture becomes 40 degree celsius calculate the temperature of hot water ​

Answer 1

Answer:

Specific heat capacity of water=4200 J/kgK

By the principle of mixtures,

m x c (T1-T) = m x c x(T-T2)

2 x 4200(80-T) = 8 x 4200(T-25)

 (4200 on both sides get cancelled)

160-2T = 8T-200

360 = 10T

T= 36 degree Celcius

Answer 2

Explanation:

actually ur answer is wrong so just don't write wrong answer as the one who is referring for him it may be confusion
