Answer 3

i think it will be solid iron because it has the least tempreture

Answer 4

Yes, as N.atia stated, the solid iron at 25°C contains molecules with the least kinetic energy. The temperature of a system is the measure of its average kinetic energy. Hence, the lower the temperature, the lower the kinetic energy.
