Question

Adding Ice to Water

An insulated beaker with negligible mass contains liquid water with a mass of 0.205kg and a temperature of 76.2?C .

Part A

How much ice at a temperature of -15.0?C must be dropped into the water so that the final temperature of the system will be 37.0?C ?

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

Explanation / Answer

(15*2100 + 334,000 + 37*4190)x = 0.205*39.2*4190
x = 33670.84/520530
x = 0.0646 kg
