To match the key terms with the provided descriptions, we can go through each description and identify the correct key term:
(1) A form of energy that is always transferred from a warmer substance to a cooler one.
- Key term: heat (b)
(2) Device that converts heat to a small amount of electric energy, often used in temperature sensors.
- Key term: thermocouple (c)
(3) A push-button barbecue lighter produces a small electric current.
- Key term: piezoelectric effect (f)
(4) Thermocouples combined to produce greater amounts of electricity.
- Key term: thermopile (e)
(5) A device, usually composed of silicon, that can be used to produce electricity from light.
- Key term: photovoltaic cell (PV) (g)
(6) Different types of metals in a voltaic cell that have different attractions for electrons.
- Key term: electrodes (h)
(7) A substance that can conduct an electric current through the movement of ions.
- Key term: electrolyte (i)
Therefore, the matched key terms are:
(1) b) heat
(2) c) thermocouple
(3) f) piezoelectric effect
(4) e) thermopile
(5) g) photovoltaic cell (PV)
(6) h) electrodes
(7) i) electrolyte
