In a two-phase 415-volt system, the heating element typically operates by converting electrical energy into heat through resistance. The rating of the heating element should be chosen based on the required power output and the specific application, commonly ranging from 3 kW to 12 kW for industrial uses. It’s essential to ensure that the element is compatible with the voltage and current ratings to prevent overheating or failure. Additionally, consider the element's material and design to optimize efficiency and longevity.
Single phase can't be turned into 3-phase by any reasonable means. But on the other hand resistance heating is fairly straight forward. If only the fuse rating is high enough it might be possible to rewire a 3-phase heater to run from a single-phase source.

The kV.A (not 'kva') rating is the total apparent power of the machine. So a 75 kV.A machine is 25 kV.A per phase.
The normal phase of an element is: What form it is (liquid ,solid ,gas) what the classification is (nonmetal ,metal ,metalloid)
No. You need a 3-phase supply that matches the voltage and current rating of your appliance.
One example of an element that sublimes on heating is iodine. When solid iodine is heated, it directly changes into a gas without passing through a liquid phase.
Single phase can't be turned into 3-phase by any reasonable means. But on the other hand resistance heating is fairly straight forward. If only the fuse rating is high enough it might be possible to rewire a 3-phase heater to run from a single-phase source.
To calculate the current draw of a 480-volt, 3-phase, 35 kW heating element, you can use the formula: [ I = \frac{P}{\sqrt{3} \times V} ] where ( I ) is the current in amps, ( P ) is the power in watts, and ( V ) is the voltage. Substituting the values: [ I = \frac{35000}{\sqrt{3} \times 480} \approx 42.1 , \text{amps} ] Therefore, the heating element will draw approximately 42.1 amps.
The normal phase for the element Mercury is Liquid.
To calculate watts, you need to multiply the voltage (in volts) by the current (in amps). For the 208 volts, 8 amps heating element: Watts = 208 volts * 8 amps = 1664 watts For the 110 volts, 8 amps heating element: Watts = 110 volts * 8 amps = 880 watts

Helium is an element that has no gas phase. It remains a gas at all temperatures, without undergoing a phase change.
It depends on the specific element and the conditions of heating. Some elements may undergo chemical reactions that cause them to gain or lose mass when heated. Others may experience changes in phase, such as melting or sublimation, which can also affect their mass.
