Question

You are provided with three watch glasses containing milk, petrol and mustard oil, respectively. Suppose you bring a burning candle near these materials one by one, which material(s) will catch fire instantly and why​

Answer 1

• The ignition temperature is also known as ignition point. Ignition temperature of a fuel can be defined as the minimum temperature to which a fuel must be heated so that it may catch fire and start burning.​
• When we bring a candle near to Petrol it will catch fire instantly because the ignition point is low, so it is highly inflammable.​​
• When we bring a candle near to milk or mustard oil it will not catch fire because it has a very high ignition temperature. So, they will not catch fire instantly.​
