What type of liquid is typically found in the capillary tube of a remote bulb thermostat?

• A. Volatile
• B. Non-volatile
• C. Conductive
• D. Inert

Answer: (A)

The liquid typically found in the capillary tube of a remote bulb thermostat is volatile. This is crucial because a volatile liquid has a low boiling point, which allows it to evaporate and expand quickly in response to temperature changes. As the temperature around the bulb rises, the liquid inside vaporizes, creating pressure that ultimately moves the mechanism of the thermostat to regulate temperature. This characteristic of volatility allows for rapid response to temperature fluctuations, giving the thermostat the ability to effectively control heating systems. The sensitivity of volatile liquids to temperature changes is what makes them ideal for this application, ensuring precise temperature regulation.
