Find the odd pair:
- ABalance : Mass
- BBarometer : Pressure
- CThermometer : Temperature
- DScrew gauge : Volume
Solution & Step-by-step Explanation
Let's analyze each pair where an instrument is mapped to the quantity it measures:
* Balance is used to measure Mass. (Correct relationship)
* Barometer is used to measure Pressure. (Correct relationship)
* Thermometer is used to measure Temperature. (Correct relationship)
* Screw gauge is used to measure thin wire diameters or thickness (small lengths), NOT Volume.
Therefore, (D) is the odd pair.
* Balance is used to measure Mass. (Correct relationship)
* Barometer is used to measure Pressure. (Correct relationship)
* Thermometer is used to measure Temperature. (Correct relationship)
* Screw gauge is used to measure thin wire diameters or thickness (small lengths), NOT Volume.
Therefore, (D) is the odd pair.
