Which type of solid has a definite melting point and is usually hard and brittle? (2022)
Step 1: Understand what a solid is. A solid is a state of matter that has a definite shape and volume.
Step 2: Learn about melting point. The melting point is the temperature at which a solid turns into a liquid.
Step 3: Identify types of solids. There are different types of solids, such as ionic solids, covalent solids, metallic solids, and molecular solids.
Step 4: Focus on ionic solids. Ionic solids are made of positive and negative ions held together by strong ionic bonds.
Step 5: Recognize the properties of ionic solids. They have a definite melting point, meaning they melt at a specific temperature.
Step 6: Note the hardness and brittleness. Ionic solids are usually hard and brittle because the strong ionic bonds make them tough, but they can break easily when force is applied.
