Instructions: 1. fill the beaker with crushed ice. suspend a thermometer in the ice so the bulb of the thermometer is close to but does not touch the bottom of the beaker. 2. record the temperature of the contents in the beaker. 3. warm the beaker with the heat source. stir gently. be careful not to let the thermometer touch the beaker. 4. record the temperature every fifteen seconds. note the states in the beaker on a separate sheet of paper each time the temperature is recorded. 5. record several temperatures at intervals as the water begins to boil. compile a summary of your findings during this investigation. be sure to answer the questions below and include your hypothesis, observations, data, interpretation, and conclusion in your report. what was the temperature of the ice before you added heat? what was the temperature as the ice melted? at what temperature did the water begin to boil? did the temperature of the water rise or remain constant as the water boiled? if the temperature did not change while heat was being added, what was happening to the ice or the water at that time? what do you think the heat was used for if not to raise the temperature? was there room for human error in your investigation? why or why not? what did you learn from this investigation? be thoughtful in your answer.
