What is thee melting point and boiling point of carbon and helium?
Answer:
CARBON
melting point :3527 º C
boiling point : 4027 º C
HELIUM
melting point: - 272.2 º C
boiling point: - 268.93 º C
Carbon :Melting point [/K]: 3800 [or 3527 °C (6381 °F)]
Helium :The melting point of Helium is -272.2 º C
carbon: melting/ 3527 C
boiling/ 4027 C
Helium: melting/ -272.2 C
boiling/ -268.93 C
The "melting point" of carbon depends on the allotrope you're dealing with.
Diamond has a melting point of 3500 deg C (at 63.5 atm) and a boiling point of 3930 deg C
Graphite on the other hand sublimes at a temperature between 3915 and 4020 deg C.
Helium has a melting point of -272.15 deg C (at 25 atm) and a boiling point of -268.935 deg C.
