Constant Volume Air Thermometer
The Constant Volume Air Thermometer is a classical physics laboratory instrument designed to measure temperature with high precision, based on the principle of maintaining constant air volume. It is widely used in physics experiments, research, and academic institutions to demonstrate the relationship between pressure and temperature in gases.
Features:-
- High Accuracy Measurement: Operates on the principle of ideal gas laws to provide reliable temperature readings.
- Robust Construction: Made from durable glass and metal components for long-term laboratory use.
- Constant Volume Design: Ensures the volume of enclosed air remains fixed, allowing direct measurement of temperature changes through pressure variations.
- Clear Scale & Readings: Equipped with a calibrated manometer for easy observation.
- Educational Use: Ideal for physics labs, colleges, universities, and research centers to study thermodynamic properties of gases.
Parts of Constant Volume Air Thermometer:-
- Bulb / Reservoir – A glass bulb filled with air (gas under study).
- Capillary Tube – A fine, narrow glass tube connecting the bulb to the manometer.
- Mercury Manometer (U-Tube) – Measures the pressure of air inside the bulb.
- Graduated Scale – Marked alongside the manometer for pressure readings.
- Water / Oil Bath – Surrounds the bulb to control and change the temperature.
- Stand / Frame – Rigid support to hold the thermometer apparatus in place.
- Clamp & Holder – For fixing the bulb and manometer securely.
- Rubber Tubing / Connectors – To ensure airtight connections between bulb and manometer.
- Heating Source – (e.g., burner or electric heater) for heating the bath.
- Pointer / Index – For accurate reading of mercury level in the manometer.
