Calculate the accurate answer of the given question
Question- An insulated beaker with negligible mass contains liquid water with a mass of 0.255 kg and a temperature of 63.7 C.
Part 1- How much ice at a temperature of -17.7 C must be dropped into the water so that the final temperature of the system will be 220 C ?
Part 2- Take the specific heat of liquid water to be 4190 J/kgK , the specific heat of ice to be 2100 J/kgK, and the heat of fusion for water to be 3.34×105 J/kg .
I need help to compute the quantity of ice.
