Column B

d.electrical to mechanical and sound

Answer 1

I can’t see the pictures you mean — please either attach them or briefly describe each object (Q, R, S, T) and I’ll match them.

If you want to try it yourself, here’s a quick way to decide which transformation fits each item:

- electrical → sound and light (a): something plugged in or battery-powered that produces both light and audible sound (e.g., a TV, phone, radio with screen, alarm clock with display).
- electrical → heat (b): an electric heater, toaster, kettle, electric stove element, hair dryer (when considered for heating rather than motor) — it converts electrical energy mainly into thermal energy.
- chemical → light and heat (c): something that burns or uses stored chemical energy to give off light and heat — e.g., a candle, a match, a wood/coal fire, a Bunsen burner.
- electrical → mechanical and sound (d): devices with electric motors or moving parts that make noise — e.g., a fan, blender, electric drill, vacuum.

Send the pictures or descriptions and I’ll give the exact matches.
