When a certain ideal gas thermometer is immersed in a water-ice mixture at 273.15 K, the mercury level in the right arm is 102 mm above the reference mark. When this thermometer is then immersed in a liquid of unknown temperature, the mercury level is 30 mm above the reference mark.

What is the temperature of the liquid?
