choose the statement below that describes the relationship between temperature and viscosity.
as temperature increases, viscosity decreases.
as temperature decreases, viscosity decreases
as temperature increases, viscosity increases.
there is no relationship between temperature and viscosity

Explanation:

For most fluids (liquids and gases, with liquids showing this more prominently), higher temperature increases molecular kinetic energy, weakening intermolecular forces (for liquids) or reducing molecular collision frequency impact (for gases in some contexts), which lowers resistance to flow (viscosity). The other options contradict this established physical relationship.

Answer:

As temperature increases, viscosity decreases.
