Demonstration- Ignition Temperature at Ulwe campus

No comments
Experiment to compare the ignition temperature of paper cup with water in it and empty paper cup was demonstrated by the teacher in class VIII A on 8.12.2017, at Ulwe campus. The candle was lighted, and a paper cup was held over the candle. In the second step, the paper cup filled with water was placed over the candle. The students were asked to touch water in the paper cup and feel the change in temperature. The paper cup in the first case has low ignition temperature, therefore, it started burning and in second case the heat from flame got transferred to water in the paper cup. It resulted in an increase in the ignition temperature of the cup. Therefore, instead of paper cup getting burnt, the water started heating up.
