A slaughterhouse preserves meat for a few weeks by keeping it at low temperatures below 5°C. Suppose meat (at 37°C) is cooled until its internal temperature is 2.0°C using an ice-water mixture. Determine the least amount of ice at 0°C required to cool 65.0 kg of meat so that the temperature of the bath is maintained at 0°C. Meat has a specific heat of 3480 J/kg°C.
You are preparing water for dishwashing at home. You place 4.50 kg of water whose temperature is 8.0°C in an insulated pale. The desired final temperature of the water is 61°C. Determine the quantity of boiling water (100.0°C) that will heat the water to the desired temperature.
