Investigation into the temperature rise of water when heated by an electric immersion heater Evaluation: I believe my investigation went well for a variety of reasons. Mainly, I feel that I have achieved reliable and accurate results and that my procedure was suitable. The method was accurate because I used accurate apparatus such as a digital stop clock that was accurate to every 100th of a second instead of a conventional clock, which is only accurate to the nearest second. I also used a voltmeter that was accurate to every 100th of a volt, making it easier for me to keep adjusting the voltage to exactly 10 (if for example the voltmeter was only accurate to the nearest volt, the voltage could have been 10.49 without me knowing, and this would have increased by a substantial amount the thermal energy of the water particles). To measure out the water I...
