When a thermometer is taken from the melting ice to a warm liquid, the mercury level rises to of the distance between the lower fixed point () and the upper fixed point (). The temperature of liquid (in ) is:

Two similar thermocouples made up of similar metals A and B are connected through a key K and sensitive galvanometer G as shown in the figure. One of the thermocouple is dipped in a hot bath maintained at temperature t2 and other one in a cold bath at a temperature t1. When the key K is pressed a deflection is seen in the galvanometer because:
