The correct answer is
Thermometer
The correct answer is Thermometer.
A thermometer is a device specifically designed and calibrated to measure temperature. The other options are incorrect because:
- Odometer: Measures the distance traveled by a vehicle.
- Hygrometer: Measures the humidity (amount of moisture) in the air.
- Voltmeter: Measures voltage (electrical potential difference).
Therefore, only the thermometer directly addresses the question of measuring temperature.
