Question

The diagram shows a thermometer used to measure temperature.



Which refers to the area on the thermometer marked with the letter A?

scale
bulb
mercury strip
number line

Answer 1

I don’t see the diagram — could you upload it or say where A is pointing?

Meanwhile, here’s how to choose the right option based on where A points:
- If A points to the round reservoir at the bottom → bulb.
- If A points to the thin column of liquid inside the tube → mercury (liquid) strip.
- If A points to the ticks/marks alongside the tube → scale.
- If A points to the row of numbers beside the thermometer → number line.
