1kg of ice at -20C is mixed with 2kg of water at 90 C. assuming that there is no loss to the environment ,what will be the final temperature of the mixture?(assume latent heat of ice is 334.4KJ/Kg, specific heat of water and ice are 4.18 kj/(kg.K) and 2.09kj/(kg.K) respectively.

(2.09)(0 + 20) + (1)(334.4) + (1) (4.18)(T)
= (2) (4.18) (90 – T)
T = 30ºC
Hope it helps
Happy learning
