Unit 5-9 Review

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

What is compression in a sound wave?

Back

Compression is the part of a sound wave where particles are grouped tightly together, resulting in areas of high pressure.

Front

What is rarefaction in a sound wave?

Back

Rarefaction is the part of a sound wave where particles are spread apart, resulting in areas of low pressure.

Front

Where does no sound exist?

Back

Sound cannot exist in space, as it requires a medium (like air or water) to travel.

Front

What is convection?

Back

Convection is the transfer of heat through currents in fluids (like air or water) where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is conduction?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or infrared radiation, and does not require a medium.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, all components are connected in a single path, while in a parallel circuit, components are connected across multiple paths.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance in a series circuit increases as more resistors are added.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.
