To reduce heat loss, we can use

• conductors

• insulators

• bulbs

• switches

Lighting circuits are examples of a

• series circuit

• parallel circuit

• insulator

• renewable technology

Current is the same at all points in a series circuit

• True

• False

• Neither

True or false.

In a parallel circuit, if one bulbs stops working they all stop working.

• true

• false

Radiation is...

• Heat energy transfer in a solid

• Heat energy in the form of a wave

• Heat energy transfer in a liquid or gas

Convection is...

• Heat energy transfer in a solid

• Heat energy in the form of a wave

• Heat energy transfer in a liquid or gas

Conduction is...

• Heat energy transfer in a solid

• Heat energy in the form of a wave

• Heat energy transfer in a liquid or gas

Heating potassium peregrinate in a beaker with a Bunsen burner results in

• green sludge in the beaker

• blue smoke

• visible convection currents

• nothing of note

examples of good insulators are

• sheep's wool

• hay

• copper

• iron

• radiation

Examples of good conductors are

• air

• nickle

• copper

• iron

• wood
