What is the characteristic of a gas?

Back

A gas has no definite volume and takes the shape of its container.

Front

What happens to the pitch of a sound when the frequency increases?

Back

When the frequency of a sound wave increases, the pitch becomes higher.

Front

What is frequency in terms of sound waves?

Back

Frequency is the number of vibrations or cycles that occur in a sound wave per second, measured in Hertz (Hz).

Front

What is the relationship between vibration speed and sound?

Back

Faster vibrations produce higher-pitched sounds, while slower vibrations produce lower-pitched sounds.

Front

What is an example of a solid?

Back

An example of a solid is ice, which has a definite shape and volume.

Front

What is an example of a liquid?

Back

An example of a liquid is water, which has a definite volume but takes the shape of its container.
