Maybe you saw one in Celsius and one in Fahrenheit. What state would sulfur be in at 200°C? In thermodynamics, the melting point defines a condition in which the solid and liquid can exist in equilibrium. A drain should be installed at the low point of the tank. Each percent of moisture in the sulfur will increase the heat load by typically 20%. Inverse vulcanization reported recently uses vinylic monomers as crosslinkers to stabilize polymers made from elemental sulfur. In thermodynamics, the term saturation defines a condition in which a mixture of vapor and liquid can exist together at a given temperature and pressure. Boiling point: The boiling point of sulfur is 444.6°C: Conductivity: A poor conductor of heat and electricity: Viscosity (resistance to flow - stickiness) Upon melting, sulfur is converted into a mobile yellow liquid, which turns brown and becomes a viscous, dark brown mass at about 190°C.

The tank or pit is fitted with an agitator which will increase the rate of sulfur melting. The raw of sulfur is generally delivered from a hopper to the melting tank or by a conveyor system. Just above its melting point, sulfur is a yellow, transparent, mobile liquid. Therefore, high-melting-point salts with low vapor pressures, low solubility of oxygen and water, such as NaCl, ... Other sulfur species, such as thiol at around 162.0 eV, were not detected in the S 2p XPS spectra. Sulfur is heated slowly and steadily from room temperature, so that all the changes in colour and consistency as it melts and eventually reaches boiling point, can be observed.
