I'm not sure but i think its the coils of wire
No and yes. In your room, no oxygen will be consumed by the electric heater, so it's safe to use it in an unventilated room. Remember, though, not to cover it to prevent overheating (and possibly fire). To create the electricity, though, it's very likely that some oxygen was used (unless you get your electricity from a renewable source: hydro, wind, etc, or nuclear). In the power station fuel is burned, so this does reduce the oxygen level, but not locally.
Of course. That's what an electric fire does, and a cigarette lighter, a toaster, a hair drier, an electric oven, a light bulb. All involve passing an electric current through a wire to make it hot.
Since an electric oven is designed for long periods of being hot I would guess quite unlikely. There could be a higher electricity bill than usual however.
No - electricity
If the gap is small then you may get 'arcing'. This is where the electricity will jump from one point to another (cable end to cable end). This could cause a fire. If the gap is too large for the electricity to jump then in effect there will be no-circuit.
it works by electricity and heat
Heat produced in a wire is directly proportional to the square of current. A wire can withstand only some specific amount of heat. When current increases above the capacity of wire/appliance,it catches fire
Yes it does you start out with electricity you get fire when you overcharge the bridge and you get ice of you pick Kuo to switch powers with
Water is a conductor of electricity, using water on an electric fire may result in electric shock, so the person putting on the water might be electrocuted as would any bystanders.

Most electric fires work by passing current through a resistance wire, made of Nichrome. It is this wire that gets hot. The wire is sometimes wrapped around, or contained within, a glass or ceramic former. This will also dissapate the heat. There are other type that work through infra red.

Electricity in electric circuits produce heat and when a circuit goes wrong the heat can escalate to the point where it causes combustion in the materials adjacent to it. This causes fires.
Safety precautions are neccessary. Incorrect use of electricity can cause electric shock and fire. Both are life threatening and a real risk.

Insulation covers the copper wires that carry electricity to prevent shorting or electrocution. Without insulation, the bare wires could cause an electrical fire, or an electric shock, possibly resulting in death.
no. 100 years ago they did not have electricity so they did not have a grill, they did use fire to cook food on though.
