this changes occurs due to temperature change .As you know temperature determines the direction of heat flow.when the surrounding temperature is high the mercury absorb some amount of heat resulting to the rise of the liquid column use in the thermometer and when surrounding temperature is low than that of the environment the liquid column drops to to heat lost to the surrounding. the surrounding can be a patient. with this property mercury is a good material for establishing a thermometer.
