Almost as hot as me.
yes, if the wood is dry and the air is hot enough
Hot enough to burn wood.
yes it will catch fire if air is too hot.
yes if there is too much fire it can get too hot
Trying to start a fire with damp wood is very difficult. When I backpack I always carry some tinder (dry shavings) to start a fire. Wet wood will not burn unless the fire is hot enough to evaporate the water that is in the wood. You can burn damp wood on an already burning fire but it will not burn as hot. Wet wood tends to smoke a lot and may go out on a small fire that does not have a good coal base. I have had to use damp wood to start a fire before but I had to shave down the wood until I found dry wood inside. Once you get a small fire started gradually add wood until you can get a hot fire. Too much wet wood at once can put out a fire. Not a good thing when you are cold and wet. Be patient.
One way for a fire to burn at a different temperature is it's wood soft wood such as pine burn fast and hot but hard wood such as muscle wood burns slower and cooler but still hot enough to burn you so don't touch it
dry wood is easily caught on fire. When wood is wet it cant catch fire. That's why when you make a camp fire you want dry wood. It lights easier and burns better.
Fire (Ex. Fire wood is forced to burn because the fire is hot) Frost
Really hot
It's technically possible, if a bit unlikely. Pellet stoves burn extremely hot, and the heated air would tend to dry out wood placed near them, making the wood more prone to catching fire.
around 1000 degrees Celsius
With a wood fire, wood gets hot. The wood turns to a gas. Oxygen from the air mixes with the gas from the wood and they create combustion. When water is added, it cools down the wood. It also turns to steam blocking oxygen from the air from getting to the wood. So water does two things. It makes the wood so it will not get hot enough to turn to gas. It stops oxygen from getting to the wood. With an electrical fire, the source of the fire is the electric current. It causes the heat. Pouring water on it will not stop the electric current and stop the heat. It will simply give the electricity more places to go. The first thing to do in case of an electric fire is turn off the electricity.
