Question

Choose all that apply. Solids, liquids, and gases can be distinguished by their?

A. Molecular Level

B. Shape

C.Temperature

D. Kinetic Energy

E. Mass

F. Density

Answer 1

Answer-

A. Molecular Level=solids have molecules tightly packed within its given volume.Strong forces of attraction binds the molecules together,

liquids have molecules freely moving but not completely free as weak attractive forces exist between them,

gases have molecules freely moving as the molecules are distant and negligible attractive forces exist between them

B. Shape-solids have fixed shape, liquid takes the shape of the container, g ases does not have any shape

D. Kinetic Energy-solids have molecules fixed in its position so they does not move ,that do not posess any kinetic energy

liquids have slightly freely moving molecules ,so it has kinetic energy and hence can flow .

gases has molecules moving very fast and freely ,so has high kinetic energy.gases diffuse from one place to another very fast

F. Density=solids have very high density as molecules are very close to each other in a given volume, so mass per unit volume is high

liquids have slightly distant molecules ,so low density than solids

gases have molecules that are far apart , so has very less molecules per unit volume or low density
