No, Pluto is not a gas planet. It is classified as a dwarf planet and is composed mostly of ice and rock.
Pluto, located in the Kuiper Belt, has a solid surface and is much smaller than the major gas giants in our Solar System, like Jupiter and Saturn. Gas planets are primarily made up of gases and lack a well-defined solid surface. They have thick atmospheres composed mainly of hydrogen and helium.
In contrast, Pluto has a rocky core surrounded by ice, and its thin atmosphere mainly consists of nitrogen, with traces of methane and carbon monoxide. This solid and icy composition, along with its size, is why Pluto does not fit the criteria of a gas planet.
