How much heat is required to change 200 mL of ice at -22°C (at typical Freezer temperature) into steam

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

the answer is b ) square root of 5

no

sodium is solid at rt
