The rate of a phase change, such as from solid to liquid, is dependent upon the specific heat of the material, the difference between the solid's core temperature and the room's ambient temperature and the application of any external energy sources such as a light bulb or heating mantle.
When a substance changes from a frozen solid to a liquid, it undergoes the process of melting. This occurs when the temperature of the solid rises above its melting point, causing the solid structure to break down and transform into a liquid state.

Example of solid changing toliquid:when you take an ice and put it to thaw out it changes to water (liquid) and is the same for liquid to solid; you freeze water(liquid) and it turns to ice (solid)
Heat will change a solid into a liquid. This process is called melting. Heat will change a liquid into a gas. This process is called vaporization. Frozen carbon dioxide, or dry ice won't melt into a liquid. It will vaporize into carbon dioxide without melting. This process is called sublimation.
Frozen ice
Because it is a frozen liquid, and since it is frozen it isn't liquid.
Water's freezing point is the temperature at which liquid water turns into solid ice, which is 0 degrees Celsius. On the other hand, water's melting point is the temperature at which solid ice turns into liquid water, also at 0 degrees Celsius. Both freezing and melting points occur at the same temperature but represent opposite phase changes.

Transformatiom from liquid water to solid water (ice).
Liquid nitrogen has no melting point. A melting point is the temperature when a solid turns into a liquid. Since liquid nitrogen is already a liquid, it has no melting point. It is already melted, compared to solid nitrogen.
The change in state from a solid to a liquid is called melting.
