Question

Gas thermometers are more advantageous than liquid thermometers because of:

• A. Proper expansion
• B. Higher accuracy
• C. Wider range of temperature scale
• D. All of the above.

Answer 1

The correct option is D All of the above.

Since gases expand much more than liquids on changing the temperature, a gas thermometer is more sensitive than liquid thermometer even for a minute change in the temperature. Hence, the measurement made by a gas thermometer would be more precise and higher in accuracy. Gas thermometers are easier to design to measure a wider range of temperature than liquid thermometers.
