Selenium melts 221.14 C on the ITS-90 Scale. Reference: Page 230 Guinness Book of Answers 9th Edition. Selenium melts at 221.18 C on the ITS-68 Scale. Reference Page 219 Guinness Book of Answers 8th Edition. T - T90 is approximately +0.011 K at this temperature according to the BIPM. T90 - T68 is approximately -0.040 K at this temperature according to Page 1-18 of the 74th Edition of the CRC Handbook of Chemistry and Physics. Page 4-122 of this Handbook gives 221 C for the melting point of Selenium. Newer editions of the CRC Handbook of Chemistry and Physics give 220.5 and 220.8 C. But these values are probably a little too low due to small amounts of impurities. The thermodynamic temperature of the melting point of selenium is 221.16 C plus or minus 0.02 C. or 494.31 K plus or minus 0.02 K. This is probably the most accurate value known for the melting point of selenium. This is for ultrapure selenium.

Selenium state of matter at room temperature?
The element, Selenium, is a solid at room temperature.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
The term defined as the temperature at which a substance changes from a solid to a liquid state is called the melting point.
What is difference between melting point and drop melting point?
The melting point is the temperature at which a solid substance transitions to a liquid state. The drop melting point is a method of determining the melting point where a small amount of the substance is heated until it melts and then allowed to drop onto a solid surface to observe the melting point. Drop melting point is often used when the substance being tested has a high melting point or when observing the melting process is critical.
The temperature at which a solid melts is called?
The temperature at which a solid melts is called the melting point. At this temperature, the solid transitions into a liquid state.
