Mars is a solid (rocky) planet. All the inner planets are solid and Mars is an inner planet.
No, Mars is only about half the size of Earth and it is a solid, rocky planet.
the earth is solid with gaseous deposits and a gaseous atmosphere.
Saturn is gaseous
The change in state would be known as melting. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition
The change in state would be known as freezing. Just for your information: Solid to Liquid = Melting Liquid to Gaseous = Boiling Solid to Gaseous = Sublimation Gaseous to Liquid = Condensation Liquid to Solid = Freezing Gaseous to Solid = Deposition
solid
It is "rocky".
Pluto is solid.
Venus is solid, but is covered in a thick gaseous atmosphere that is many kilometres thick.
From solid to liquid, from liquid to gaseous, from gaseous to liquid, from liquid to solid, and in sublimation from solid to gaseous or the reverse, chemical properties do not change.
