Question

how does temperature affect the density of water

Answer 1

Explanation:

Density is a physical property of substances that compares the relationship between volume and mass. Density is affected by temperature because as temperature increases so does the kinetic energy of the particles.

Cooling a substance causes molecules to slow down and get slightly closer together, occupying a smaller volume that results in an increase in density. Hot water is less dense and will float on room-temperature water. Cold water is more dense and will sink in room-temperature water.
