Column B
a.electrical to sound and light

d.electrical to mechanical and sound

Answer 1

I don't have the descriptions or pictures for Q, R, S and T — could you paste them or upload the image?

Meanwhile, here are quick identification hints so you can match them once you provide the objects:

- electrical → heat (b): heating element appliances: electric kettle, toaster, electric heater, hair dryer on heating setting. Look for devices that get hot and primarily produce warmth.
- electrical → sound and light (a): devices that run on electricity to produce both sound and visible light (e.g., a doorbell with a flashing light, some electronic toys, a radio with an indicator light). Look for items that clearly produce both a noise and a glow.
- chemical → light and heat (c): combustion/chemical reactions that give off flame/light and heat: candles, matches, burning wood, a gas stove flame. Look for items that burn or have a chemical fuel.
- electrical → mechanical and sound (d): electric motors that produce motion and some noise: electric fans, drills, motor toys, blenders. Look for moving parts driven by electricity that also make noise.

Send the object descriptions (or the image) and I’ll match Q–T to a–d.
