<ul><li>Measuring temperature without a thermometer can be achieved using calorimetric method.</li><li>The principle involves heating up an object of known mass and composition with a high temperature flame.</li><li>By measuring the temperature change of water after the object is submerged, the original temperature of the object can be calculated.</li><li>The method demonstrated in the video estimates the flame temperature to be about 600°C, although typical natural gas-powered burners reach temperatures around 1,500°C.</li></ul>
