Answer 2

⏭ Your Answer:

• Option C

➙ Boiling point is above room temperature and melting point is below room temperature$.$

⏭ Explanation:

For understanding this concept, let's consider an example. We know that, normal room temperature is 25°C. Water is a liquid at room temperature because it's melting point is 0°C which is below the room temperature and boiling point is 100°C which is above the room temperature.

⭐ Similarly,

• If melting point and boiling point both are above the room temperature, then it will be in solid state at room temperature.
• If melting point and boiling point both are below the room temperature, then it will be in gaseous state at room temperature.

✒ Some properties of liquid state are:

• They have no fixed shape. They takes the shape of the container.
• But they have fixed volume.
• Liquids have fluidity, not rigidity.
• They have lesser density as compared to solid.
• The kinetic energy of the particles of liquid is more than that in the solid state.
• The particles have more interparticular spaces as compared to that in solids.
• Particles in the liquid can diffuse easily.
