Which description correctly links the properties of gases to their behavior at the particle level?
Gases have stronger intermolecular forces than solids
Gas particles have more mass than solid particles
There is more space between particles in gases than in solids
Gas particles are larger than solid particles
Homogeneous mixtures can only be solids
The components of a homogeneous mixture are chemically bonded
A homogeneous mixture has uniform composition throughout
A heterogeneous mixture contains only one visible phase
Filtration
Distillation
Paper chromatography
Evaporation
Elements can be separated by chemical means
Compounds consist of only one type of atom
Elements have variable composition
Compounds are made of two or more elements chemically bonded
High compressibility due to large particle size
Low density due to weak covalent bonds
Expansion on heating due to increased kinetic energy of the particles
Constant volume due to restricted movement of particles
