Flashcards

What is a fluid?

The ability of a fluid to flow. Liquids and gases are considered fluids because they can change shape and move freely.

What is viscosity?

A measure of a fluid's resistance to flow. It describes how thick or thin a fluid is.

How do attractive forces affect viscosity?

The stronger the attractive forces between particles in a fluid, the more viscous the fluid. This is because the particles are held together more tightly, making it harder for them to move past each other.

How does temperature affect the viscosity of a liquid?

Increasing the temperature of a liquid generally decreases its viscosity. This is because the particles move faster and have less time to interact with each other.

How does concentration affect the viscosity of a liquid?

Increasing the concentration of a substance dissolved in a liquid increases its viscosity. This is because the dissolved molecules add more mass to the liquid, making it harder for the particles to move past each other.
