FAQs on Solids, Liquids and Gases - 2 Class 5 Worksheet Science

1. What are the three states of matter?
Ans. The three states of matter are solids, liquids, and gases. These states are determined by the arrangement and movement of particles.
2. How do solids, liquids, and gases differ from each other?
Ans. Solids have a fixed shape and volume, with particles tightly packed together. Liquids have a fixed volume but can change shape, with particles that are close together but able to move. Gases have neither a fixed shape nor volume, with particles that are far apart and move freely.
3. What causes matter to change from one state to another?
Ans. Matter changes from one state to another due to changes in temperature and pressure. Increasing temperature can cause a solid to melt into a liquid, and further increasing temperature can cause the liquid to vaporize into a gas. Decreasing temperature can cause a gas to condense into a liquid, and further decreasing temperature can cause the liquid to freeze into a solid.
4. Can matter exist in more than one state at the same time?
Ans. Yes, matter can exist in more than one state at the same time. For example, during a phase change, such as melting, there can be both solid and liquid particles present. This occurs because the particles at the surface of the solid gain enough energy to overcome the forces holding them together, while the particles in the center of the solid remain tightly packed.
5. How does the behavior of particles differ in solids, liquids, and gases?
Ans. In solids, particles vibrate in fixed positions and have the least amount of energy. In liquids, particles are able to move past each other and have more energy than particles in solids. In gases, particles move rapidly and independently, colliding with each other and the walls of their container, and have the most energy among the three states of matter.
