Metal is melted at 1,300°C.
Metal is melted at 1,300°C.

Metal is cooled at 1,300°C.
Metal is cooled at 1,300°C.

Metal is heated from room temperature to 200°C.

Answer 1

I would go with b and d.
b. When a solid is melted, the solid particles move around faster due to increasing kinetic energy making it easier to break the intermolecular forces holding the solid together which allows the liquid to form.
d. Increasing the T from room T to 200 C obviously increases the KE of the particles due to T difference.
