If the initial temperature of the tea is 175̊F, what would the final temperature of the tea be once the ice cubes have completely melted? Specific heat capacity of tea = 4.019 kJ/kg K Weight of ice cubes = 65 grams total weight Initial temperature of ice cubes = - 18 C Weight of tea = 400.0 grams

    is it 150.48 F ...not sure how the heat capacity comes into play seems to be more on the physics type of a question

    basically took a weighted average using the weights of tea and ice cubes relative to total weight **-18C = -.4F -->175(400/465) -.4(65/465)
