They do work, they use the Stefan-Boltzmann law (related to radiation of hot bodies)
Yes. Straightening irons with ceramic plates distribute heat more evenly and lock in moisture. The ceramic also allows the device to heat and cool quickly and easily.
Yes, the heat definitely kills germs.
they put the salt water in a large bowl with heat plates, turn on the heat plates, theres also a cap above the bowl also in a semicircle shape, the water boils, steam, liquify on the cap, and drip off the cap into another bowl, this can be observed in The Powder Toy.
Hot plates work when u plug in the cord into the electrical output. Or if u have the new $1,000 hot plate that gets hot without having to plug in the wall just turn up the knob.
Grounding plates work better in the desert areas because of the vast land.
No, a heat engine is not a device that converts work into heat. It is the opposite, which means it is a device that converts heat into work.
The usual printer for this type of work is a thermal transfer printer where a roll of coloured plastic film is transferred by heat to the plastic label.
Yes, IF they are installed to fully meet the specifications of the manufacturer, AND IF the reflecting surface is kept clean.
No, it changes according to heat. For example if you hold in tightly in your hands, it will change colour.
I bet it would work but it would take really high heat and a lot of light
Yes they work well if the room is insulated well but if it is not sealed well then it doesn't heat as effectively and it takes quite some time to heat up a cold room.
Electrostatic air purifiers work by charging the air particles. The air particles then are attracted to collecting plates and stay there until the plates are cleaned
