A copper container of mass 0.300kg contains 2.0 kg of lemonade at 33degree Celsius. 0.45kg of ice at -5 degree Celsius is poured into the lemonade. Assuming no heat is lost surroundings. What is the final temperature of the lemonade? Specific heat of lemonade = 4186 j/kg.K, Copper = 387j/kg.K, ice = 2090 j/ kg.k and latent heat of fusion = 3.33*10^5 j/kg
