Module 14 Review

Front

What does the term 'liquid' refer to?

Back

A state of matter that has a definite volume but no definite shape, taking the shape of its container.

Front

What is the boiling point of a substance?

Back

The temperature at which a liquid turns into vapor; for water, it is typically 100°C at standard atmospheric pressure.

Front

What is viscosity?

Back

A measure of a fluid's resistance to flow; higher viscosity means a thicker fluid that flows more slowly.

Front

What is Bernoulli's principle?

Back

The principle that states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.

Front

What is Pascal's principle?

Back

The principle that states that when pressure is applied to a confined fluid, the pressure change occurs throughout the entire fluid.

Front

What is Archimedes' principle?

Back

The principle that states that an object submerged in a fluid experiences a buoyant force equal to the weight of the fluid displaced by the object.

Front

What is the difference between solids, liquids, and gases?

Back

Solids have a definite shape and volume, liquids have a definite volume but take the shape of their container, and gases have neither definite shape nor volume.

Front

What is the significance of a heating curve?

Back

A graph that shows the change in temperature of a substance as it is heated, illustrating phase changes such as melting and boiling.

Front

What happens to the pressure of a fluid when it is compressed?

Back

According to Pascal's principle, the pressure increases uniformly throughout the fluid.

Front

How does temperature affect the viscosity of a liquid?

Back

Generally, as temperature increases, the viscosity of a liquid decreases, allowing it to flow more easily.
