Question 123

A piece of solid gallium at its melting point of 30∘C30^\circ\text{C}30∘C is placed into a warm container of water at a temperature of 45∘C45^\circ\text{C}45∘C.

After a short time, some of the gallium has melted and the water has cooled to a temperature of 40∘C40^\circ\text{C}40∘C.

What is the temperature of the remaining solid gallium?

A
