Why is Steel weak to Fire?
No, but it can weaken and bend with intense heat. Perfect example of that is the World Trade center on 9-11. The steel girders in the towers became weak because of the intense heat from the jet fuel and the connecting bolts became weak. As the stresses from the heat and weight of the floors above got worse the building collapsed in on it's self and as the floors above went it took the floors below with it. Just like a "house of cards".
What temperature does wood spontaneously catch fire?
Wood catches fire at 540 degrees Fahrenheit. Prior to this temperature, wood does not produce any heat, but forms gases like carbon dioxide, carbon monoxide and also forms acetic and formic acids.
Why do things catch on fire?
Fire needs three things to start and sustain itself... fuel (matter), Oxygen and heat. Take away one of the three and no fire. The amount of energy needed to start something on fire is known as it's flash point.
Why does spaceships catch on fire while coming back to earth?
It has a high speed as it begins re-entry, but the earths atmosphere slows it down as it approches the surface. The heat comes about due to the friction of the atmosphere on the shuttle as it slows.
What properties does a slipper have to control fire?
You can normally control a *very small* fire by hitting it with your slipper because it will be starved of oxygen and momentarily cooled. Fire needs 3 things: Fuel, oxygen and heat. By hitting it with your slipper, you will take away some of it's heat, and you will starve it of oxygen.
Why a piece of paper wrapped around an alluminium pipe does not catch fire easily?
The metal (your aluminum) will attempt to carry the heat away from the paper.

Why can coal dust in mines catch fire?
The coal dusts have large surface area thus it can easily absorb the heat and reach its ignition temperature and thus can burn easily... Remember a wood fillings can be easily burned in seconds but a wood block cannot be burnt easily as it takes time to transfer heat to all its body and thus reach the ignition temperature...
During distillation of ether why you used water bath for heating?
Because ether is highly volatile liquid and easily catch the fire (combustible) so direct heat on flame is not possible.
How do you use properly devices and equipment that produce heat?

Can you use a heat lamp bulb in a regular socket in the bathroom?
You sure can, it's been done, and the bathroom didn't blow up, the bathroom was just extremely bright Some sockets, though, do have a maximum wattage and/or a maximum heat tolerance that needs to be followed to avoid the risk of fire in the wiring and ceiling. It won't blow up, but you might start a fire. Heat lamps should have a porcelain socket and heat resistant insulation.
