1.Most substances are denser in their solid state. For example, solid Fe will sink in liquid Fe. When they freeze into solids they form tightly-packed crystals that are much denser than the liquid was originally. When solid, the molecules move slower and have less energy to resist attraction to each other. Options: 1. TRUE 2. FALSE 2.Paint is a pigmented opaque material that completely covers and hides the surface to which it is applied. In a paint, the function of a drier is to dissolve the paint and reduce viscosity of paint or thin it for use in sprayer applicators or when simply needing a thinner mixture to work with. Options: 1. TRUE 2. FALSE 3.Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances. Cohesion is the attraction of molecules of one kind for molecules of a different kind, and it can be quite strong for water. Adhesion refers to the attraction of molecules for other molecules of the same kind. Options: 1. TRUE 2. FALSE 4.Hydrogen bonding is important in various chemical processes. Hydrogen bonding is responsible for water's unique solvent capabilities. Water molecules stick to each other because a single water molecule may be involved in as many as three hydrogen bonds at the same time. Options: 1. TRUE 2. FALSE
