I assume your melting point is -114C..otherwise mp is higher than boiling point.
See below


At 60C, your substance will be a liquid (it is still lower than the the boiling point, and higher than the freezing/melting point). All liquids have some vapor pressure, though, so your substance will also partially be in the gas phase.

Substance will be mostly liquid with a little bit as gas.
