Do different phases of the same substance have the same specific heat capacities? Can someone please explain this?
This is related to heat of fusion (energy needed to change state at constant temp), not specific heat capacity (energy needed to raise the temperature by a certain amount without changing state).I'll throw this in from TBR; liquids have the highest heat capacity because in liquids to gases you're breaking intramolecular bonds so you're going to need a lot of energy, compared to solid->liquid where you're just weakening bonds.
Whoops, carry on then.
Wait, so they have the same heat capacities or they don't have the same?
