Answer 1

CERTIFIED ANSWER. In a clinical thermometer kink plays an important role. kink prevents the mercury present in the capillary to fall back in the bulb. So it separates the mercury at high temperature and cool mercury and allows the user to note the reading when the thermometer is taken out.
