If the building absorbed so much heat that it turned into a liquid, then it would have undergone a phase change known as "melting."
Phase changes occur when a substance is heated or cooled, causing its particles to rearrange and change their arrangement. In this case, the building started as a solid and turned into a liquid due to the high amount of heat it absorbed.
To determine the correct phase change, we need to understand the basic phases of matter:
1. Solid: A substance with a fixed shape and volume, where the particles are closely packed together and vibrating in place. Example: Ice.
2. Liquid: A substance that flows and takes the shape of its container, with particles that are more loosely packed and move more freely. Example: Water.
3. Gas: A substance that has no fixed shape or volume, with particles that move rapidly and are far apart. Example: Steam.
In this case, when the building absorbed enough heat to melt, it transitioned from a solid state (building) to a liquid state (molten building). Melting occurs when a solid absorbs enough thermal energy to break the bonds holding its particles together, resulting in a change from a rigid structure to a flowing liquid form.
So, the phase change that the building would have undergone is called "melting."
