Hello Mate Here is your answer !
Answer :
Answer 1 ) - Wood does not burn with a burning matchstick because the ignition temperature of the wood is high and matchstick burns out soon. It needs to he heated for a longer period so, it does not burn with burning matchstick.
Answer 2 ) - Ignition temperature of wood depends on the exposure time, moisture, density and the type of wood. Therefore wood doesn’t have a fixed ignition temperature. This is also the case in paper.
Answer 3 ) - A matchstick does not catch fire and burn on its own at room temperature because the ignition temperature of matchstick is higher than the room temperature.
Answer 4 ) - The temperature for the piloted ignition of wood is typically about 350 °C, whereas the spontaneous ignition requires a temperature of approximately 600 °C.
Answer 5 ) - A matchstick does not catch fire and burn on its own at room temperature because the ignition temperature of matchstick is higher than the room temperature.
