Quick vs slow freezing

WebThus we can state that cooling effect of hot water is more than cooling effect of cold water. There is also one more thing that affects the rate of cooling. As the differences between the temperature of surroundings and the temperature of liquid is more in hot water than in cool water, hot water again cools faster than cold water. Share. WebDepending on the freezing rate, larger (slow freezing) or smaller (fast freezing) ice crystals out of the immobilized and free water will be formed [13] and they are capable of …
