A gas thermometer is more sensitive than a liquid thermometer because a gas :

A. Is lighter than liquid

B. Expands more than a liquid

C. Is easy to obtain

D. Does not change state easily

Answer: Option B

Solution (By Examveda Team)

Since gas expands much more than liquid on changing the temperature. Thus a gas thermometer is more sensitive than liquid thermometer as gas can expand more even in very small change in temperature. So the measurement has to be precised.
