• Matter can change its state from solid to liquid to gas and vice versa

Gas$\bf\color{magenta}{cool⤳}$liquid$\bf\color{magenta}{freeze⤳}$Solid

$\bf\color{magenta}{---------------}$

• Effect on temperature: On increasing the temperature, the particles gain energy and start vibrating with greater energy. Due to increased kinetic energy the particles overcome the force of attraction and a new state is obtained..
• Melting point:The minimum temperature at which a solid melts to become liquid at the atmospheric pressure is called melting point..
• Boiling point: The temperature at which a liquid starts boiling at the atmospheric pressure is known as boiling point. Boiling point is a bulk phenomena..

Answer 2

1.A solid is a condition of matter with a defined shape and volume, whereas a liquid has volume but no defined shape.

2.A liquid adopts the shape of the container in which it is contained, but a solid has its own shape.

3.The atoms in a solid are strongly tied together, forcing it to compress and allowing it to only vibrate, but the atoms in a liquid are temporarily connected together, allowing them to flow.

4.In contrast to liquids, solids are robust, elastic, ductile, and flexible.

5.Liquids are employed as solvents, lubricants, power producers and transmission, and measuring instruments, whereas solids are used as construction materials, heat and energy conductors, and insulators, among other things.

Water, oil, mercury, and ethanol are examples of liquids, while wood, stones, trees, and soil are examples of solids.
