Yes, using an electric bar heater to heat a room involves a physical change. The heater converts electrical energy into thermal energy, warming the air in the room. This process does not alter the chemical composition of the air or the heater itself, but simply changes the temperature and energy state of the air molecules. Thus, it is considered a physical change rather than a chemical one.
It is a chemical change which manifests a physical effect of gas being evolved from a liquid. If the gases already existed and were just coming out of solution, it would be a physical change, but since it is a change from water molecules to oxygen and hydrogen molecules it is definitely a chemical change, not a physical one.
A fan interlock relay can be used to prevent the electric heater from being energized when the fan is not running. This relay will only allow power to the heater when the fan is operating, ensuring that the heater cannot operate independently.

That is a physical change - at least the pump is (air in, air out, with no chemical change). The energy required to run the pump probably will come from a chemical reaction though: an electric generator burning fuel to run the generator or food being digested and converted to energy in the muscles if it is a person powering it
Yes this is a physical change because they are melting it and then it's being changed by the heat of the torch but heat is a physical change.
No if your heater is electric you can not use a gas heater you have to use the electric heater and it would really cause too much to change over from electric to gas so I would truly stick to what heater you have noiw
The glowing of an electric bulb is a physical change. This is because the light produced is a result of energy being converted into electromagnetic radiation, without any change in the chemical composition of the bulb's components.
Flat tires is a sign of physical change. The tires go from being normal, to then being flat. This changes their physical form.
physical change plain and simple

Physical Change
Cutting anything is a physical change.
Gas heaters are slowly leaving the industry and are being replaced by electric heaters, which are created by Chromalox. However, by using an electric heater, electric bills get expensive.

no, its physical change :)
