No. While comets contain some rock, they are mostly made of ice.
It is solid ice and rock. The ice melts as it's coming near the sun though.
The celestial form made of frozen gases and solid rock is called a comet. Comets typically have a nucleus of rock and ice surrounded by a glowing coma and sometimes a tail when they come close to the sun.
The nucleus is the solid part of a comet.

The center of a comet is called its nucleus.
The tail of a comet is made up of a combination of frozen rock, and ice particles coming off the comet and is lit up by the sun. If you were to be in this tail, you would face: subzero temperatures and constant pummeling by SOLID ice and rock.
Rock: asteroid. Liquid: none. Gas: comet.
The solid object at the head of a comet is called the comet nucleus.
The dense section of a comet's head is called the nucleus. It is composed of ice, rock, and dust, typically ranging in size from a few hundred meters to tens of kilometers. The nucleus is the solid core of the comet from which gas and dust are released to form the comet's coma and tail when it gets closer to the Sun.

The heart, or center of a comet is called the nucleus. The nucleus is made of a solid piece of ice surrounded by a cloud of particles and gases.
