What else can I help you with?
Which solids could not have two parallel face?
cone
What is intersection of solids?
The intersection of two or more solids can either be an empty set, a point (two cones "intersecting" apex-to-apex), a line (two cubes touching along one edge), a face (two cubes, face-to-face). If the solids are "filled", the overlapping intersection will be another solid. If they are hollow, it will be a closed three dimensional figure.
What do two tetrahedrons joined face to face make?
A regular triangular dipyramid. It is one of the 92 "Johnson solids". Those are the convex polyhedra whose faces are regular polygons, but do not belong to either of the two sets of highly symmetric polyhedra (the Platonic and the Archimedean), or to the perhaps less interesting two infinite families of prisms and antiprisms.
What is always less dense than solids?
Gases are less dense than solids.
Why vapour pressures of solids are far less than those of liquids?
The vapour pressure of solids are far less than those of liquid because solids have fixed arrangement of molecules and between atom of solids their is strong intermolecular forces that held the molecules in place and the molecules of liquid have less intermolecular forces as compared to solids.
What platonic solids do not have a triangular face?
A cube and a dodecahedron.
What are the two types of solids?
The two types of solids are amorphous and crystalline solid!

Which geometric solids has one circular face and no vertices?
Cone
What geometric solids has one circular face and no vertices?
sphere
What is two tetrahedrons stuck together called?
Two regular tetrahedrons connected face to face make a "regular triangular dipyramid." That is one of the 92 "Johnson solids." Those are the convex polyhedrons whose faces are regular polygons but do not belong to either of the two sets of highly symmetric polyhedrons (the Platonic and the Archimedean) or to the perhaps less interesting two infinite families of prisms and antiprisms. If the two tetrahedrons overlap, both centers at the same place but with the tetrahedrons facing in opposite directions, it makes a "stellated octahedron."
