Question

experimentally show that ignition temperature is required for combustion​

Answer 1

Answer:

If you limit the amount of air available, the candle's flame eventually goes out once it uses up all the oxygen. Air is essential for burning fuels as oxygen is an essential component for burning or combustion process and oxygen is composed in the air so air is essential for burning fuels.

:Three things are required in proper combination before ignition and combustion can take place---Heat, Oxygen and Fuel.

There must be Fuel to burn.

There must be Air to supply oxygen.

There must be Heat (ignition temperature) to start and continue the combustion process.

:Autoignition point of selected substances

Substance Autoignition Note

Magnesium 473 °C (883 °F)

Molybdenum 780 °C (1,440 °F) 780±5

Paper 218–246 °C (424–475 °F)

Phosphorus,white 34 °C (93 °F)
