Purpose:Demonstrate quantitatively the conversion of electrical energy into heat.
Description:This old-style 200-watt immersion heater is used to heat approximately 200 ml of water in a borosilicate beaker. Measure the initial water temperature with a digital thermometer, allow it to heat for a fixed time, then measure the final temperature. A calculation of the energy used should come to within approximately 10% of the predicted result.
Note that the heater will (obviously) get hot! Do not allow it to burn your hand or the power cord.
Loc codes:K6, I0
