Kevin's Math Question

2.1) Q19. The table includes the melting points and boiling points of six elements known as the noble gases.
Measured in Celsius
Noble Gas : Melting point : Boiling point
Argon : -189.2 : -185.7
Helium : -272.2 : -268.6
Neon : -248.67 : -245.92
Krypton : -156.6 : -152.3
Radon : -71.0 : -61.8
Xenon : -111.9 : -107.1

A) The noble gases that have a melting point that are less than the melting point of argon are helium and neon which are at -272.2 and -248.67 Celsius.

B) The noble gases that have a boiling point that are greater than the boiling point of krypton are radon and xenon which have boiling points of -61.8 and -107.1 degrees Celsius.

C) The melting points in ascending order are :
Helium(-272.2), Neon(-248.67), Argon(-189.2), Krypton(-156.6), Xenon(-111.9), Radon(-71.0)

D) The boiling points in descending order are :
Radon(-61.8), Xenon(-107.1), Krypton(-152.3), Argon(-185.7), Neon(-245.92),
Helium(-268.6)
