Solution
The correct option is D melting
When a solid is heated, the particles are given more energy and start to vibrate faster. At a certain temperature, the particles vibrate so much that their ordered structure breaks down. At this point the solid melts into liquid. This temperature change from solid to liquid is called the melting point. Each solid has a set melting point at normal air pressure, but at higher altitudes the melting point lowers.
