Fluorine (F) will have properties similar to Bromine (Br) because it belongs to the same group as Bromine.
8.9 g + 90 g = 98.9 Copper has a density
Answer:
Particles of matter possess energy called kinetic energy.
Solid cannot be compressed, but gases are highly compressible.
The Kinetic energy of molecules of gases is very large & solids the least.
On heating a sublimable liquid, the molecules break free & escape from the surface of the solid directly into vapour.
Particles of matter move more rapidly on the application of heat
