Introduction Heat and temperature are often confused. Temperature refers to the quantity of molecular kinetic energy that a piece of matter has. Heat, on the other hand, refers to the a mount of thermal energy transferred. Heat energy may be converted to or from another form of energy. Materials pot, stove, ice, water, stopwatch, thermometer (with a temperature range of at least -20 degrees Celsius to 120 degrees Celsius) Procedure 1. Fill a pot with about half water and half ice. Wait a minute, then stir the water. 2. Place the thermometer in the water, and turn on the burner. Time with a stopwatch how long it takes for the temperature to reach 10C. Keep the water well-stirred so that there are not hot and cold spots in the liquid. 3. Continue heating the water for that same amount of time again, and record the temperature change. 4. Start again, only this time only use half the amount of ice (the same amount of water as before). Record the numbers again
