Question

An insulated beaker with negligible mass contains liquid water with a mass of 0.230 kg and a temperature of 66.4 ∘C .

a)How much ice at a temperature of -23.3 ∘C must be dropped into the water so that the final temperature of the system will be 23.0 ∘C ?

Take the specific heat of liquid water to be 4190 J/kg⋅K , the specific heat of ice to be 2100 J/kg⋅K , and the heat of fusion for water to be 3.34×105 J/kg .
