About This Product
On this HEAT TRANSFER LAB apparatus, current passed through the test wire heats it while it is surrounded by water of constant temperature. As the voltage is adjusted with the dimmerstat, the temperature difference between the wire surface and the water produces the different pool boiling regimes, observed with the table light until the burnout point.
