Molten sulfur assumes a dark red color above 200 °C.
no
Lava is actually just rock in its liquid form - it's not sulfur. If it were, you would know it because at the temperature of lava, it burns and produces the nasty-smelling gas sulfur dioxide. You'll start gagging and coughing from the smell when you get anywhere near a molten-sulfur flow.
orange
Yes, Sulfur dioxide turns moist litmus paper from blue to red.
Yellow and silver
Sulfur (or sulphur) is a yellow solid at room temperature and a red liquid when molten.
no
Lava is rock so hot that it is liquid and is at the surface of the Earth.

No, because molten sulfur is not ionic or metallic, so even if it did conduct, it would be a very, very poor conductor.
The element copper can conduct electricity. These are two completely different chemical substances.
Sulfur dioxide is a gas at room temperature.
The melted sulfur is red-brown.
Sulfur is extracted by two main processes: Sicilian and Frasch. Sicilian- powdered sulfur is put on the top of the deposit and ignited. AS it burns the sulfur melts from the heat causing the molten sulfur to flow down the hills. Cool huh? Frasch- uses pipes to heat the sulfur, air compresses it (to foam) and it flows out the pipe.
no it is a chemical change

Molten rock glows red because it is extremely hot. Glowing due to high temperature is called incandescence.
