What happens when a fluid cools down?
What happens when a fluid cools down? Answer: When the fluid cools, the kinetic energy of the molecules decreases. This causes the molecules to slow down and move closer together. Since the molecules are closer together, the density of the fluid increases and the fluid sinks. What best describes how fluids change as they travel? […]
