Study Set #8

Front

What is a solid?

Back

A state of matter where particles are closely packed together in a fixed arrangement, resulting in a definite shape and volume.

Front

What is a liquid?

Back

A state of matter where particles are close together but can move past one another, allowing liquids to take the shape of their container while maintaining a definite volume.

Front

What is a gas?

Back

A state of matter where particles are far apart and move freely, resulting in no definite shape or volume.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, which can occur through a vacuum, such as sunlight warming the Earth.

Front

What happens to particles in a solid when heated?

Back

They gain energy, vibrate more, and may eventually change to a liquid state.

Front

What happens to particles in a liquid when heated?

Back

They gain energy, move faster, and may eventually change to a gas state.

Front

What happens to gas particles when cooled?

Back

They lose energy, move slower, and may eventually condense into a liquid state.

Front

What is the process of heat transfer in a pot of boiling water?

Back

Convection, as warm water rises and cool water sinks, creating a circular current.
