What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow. A liquid with high viscosity, like honey, flows slowly.

What is the process called when a solid changes to a liquid?

Back

Melting is the process where a solid turns into a liquid when it is heated.

What is the process called when a liquid changes to a solid?

Back

Freezing is the process where a liquid turns into a solid when it is cooled.

Front

What is boiling?

Back

Boiling is a type of vaporization that occurs both below and on the surface of a liquid.

Front

What is a solid?

Back

A solid is a state of matter where particles are closely packed together in a fixed arrangement, either crystalline or amorphous.

Front

What is evaporation?

Back

Evaporation is the process where liquid turns into vapor at the surface, usually at temperatures below boiling.

Front

What is condensation?

Back

Condensation is the process where vapor turns back into liquid, often when it cools down.

Front

What is sublimation?

Back

Sublimation is the process where a solid changes directly into a gas without becoming a liquid first.

Front

What is the difference between boiling and evaporation?

Back

Boiling occurs at a specific temperature throughout the liquid, while evaporation can happen at any temperature at the surface.

Front

What happens to particles during melting?

Back

During melting, particles gain energy and move apart, transitioning from a solid to a liquid state.
