Gas thermometers are preferred over liquid thermometers because;
- gas expands more than liquid, hence gas thermometers are more sensitive than liquid thermometers.
- in a single thermometer different gases can be used.
- all the gases have same cubical expansion coefficient.
- little impurity in the gases has little effect on the temperature being measured.
