# Melting point of the hydride

This gives the melting point of the hydride.

K (Kelvin)

## Notes

In many cases such as CH4, of course, the term hydride in not used.

Other temperature scales include the centigrade (Celsius) scale and the Fahrenheit scale. The size of one degree is the same on the Kelvin scale (K) as on the centigrade scale (°C). The zero point is different:

temperature (K) = temperature (°C) + 273.15

Thus, the melting point of water is = 0°C = 273.15 K and the boiling point of water is = 100°C = 373.15 K

On the Fahrenheit scale (°F), the melting point of water = 32°F while the boiling point = 212°F.

Therefore the degree size is different on the Fahrenheit scale with 180 Fahrenheit degrees = 100 centigrade degrees. Conversion between centigrade and Fahrenheit is achieved using the following relationship:

temperature (°C) = [temperature (°F) -32] * 5/9

You can look at visual representations of melting points, boiling points, and the liquid range using the following links.
