Answer 1

Statement 1 is true but statement 2 is false.

* In case of electrical appliances with metal bodies, the third pin is present as a safety measure( for earthing purposes).

* In situations where there's a leakage of electricity to the body of the appliance, the extra charge flows to the earth and thereby prevents electrocution.

* Therefore, the first statement is true but the second statement specifying the reason for it is incorrect as there's no case of prevention of heating in the wires.
