Question

An insulated beaker with negligible mass contains liquid water with a mass of 0.270 kg and a temperature of 64.8 ∘C

Part A: How much ice at a temperature of -23.9 ∘C must be dropped into the water so that the final temperature of the system will be 34.0 ∘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
