Surface Temperature (K)
A Barnard's Star is less bright than the sun has a surface temperature below 3,800 K,
and is red
B Barnard's Star is less bright than the sun, has a surface temperature above 3,800K,
and is red
C Barnard's Star is brighter than the sun, has a surface temperature below 5,300 K
O and is llow. Barnard's Star is brighter than the sun, has a surface temperature
above 5,300 K, and is yellow
D Barnard's Star is brighter than the sun, has a surface temperature above 5,300 K
and is yellow

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
