could someone please explain this statement in 11th ncert textbook :liquid in glass thermometers show different readings for temperatures other than the fixed points because of differering expansion properties. a thermometer that uses a gas however gives the same reading regardless of which gas is used. experiments show that all gases at low densities exibhit same expansion properties............also what is absolute zero and triple point
