Topic 2 Lesson 1-Neal

Front

What is viscosity?

Back

A liquid's resistance to flowing.

Front

How does viscosity affect the pouring speed of a liquid?

Back

The higher the viscosity, the slower it pours.

Front

What is surface tension?

Back

The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together.

Front

What happens to the surface of a liquid due to surface tension?

Back

It causes the surface to act as if it has a thick skin.

Front

What does it mean to be compressed?

Back

Squeezed or pressed together.

Front

What happens to the particles in a solid?

Back

Particles vibrate in place, atoms are closely spaced, and atoms do not change relative locations.

Front

What happens to the particles in a liquid?

Back

They move around in a confined space, and molecules are widely spaced except when they happen to collide.

Front

What is a characteristic of solids?

Back

They have a definite shape and a definite volume.

Front

What is a characteristic of liquids?

Back

They have no definite shape but have a definite volume.

Front

What is the relationship between viscosity and temperature?

Back

As temperature increases, viscosity typically decreases.
