1. Things with a mass and occupy space are known as………………
✔ Answer: matter
> Explanation: Matter is anything that has mass and takes up space (volume). This is the basic definition of matter.
---
2. Things without a mass and do not occupy space are known as………………
✔ Answer: energy
> Explanation: Energy does not have mass and does not take up space. For example, light, heat, and sound are forms of energy.
---
3. A……………… has no definite shape or definite volume.
✔ Answer: gas
> Explanation: Gases expand to fill their container — they have neither fixed shape nor fixed volume.
---
4. A……………… has a definite shape and definite volume.
✔ Answer: solid
> Explanation: Solids maintain a fixed shape and volume due to strong intermolecular forces.
---
5. A……………… has a definite volume but no definite shape.
✔ Answer: liquid
> Explanation: Liquids have a fixed volume but take the shape of their container.
---
6. The ability of a metal to be drawn into thin sheet without breaking by hammering or rolling is known as…………………
✔ Answer: malleability
> Explanation: Malleability is the property of a material (especially metals) to be deformed under compressive stress, like being hammered into sheets.
---
7. The water found in seas and oceans is known as …………………water.
✔ Answer: marine
> Explanation: "Marine" refers to anything related to the sea or ocean. So, seawater is called marine water.

8. The water found in lagoons is known as………………….. water.
✔ Answer: brackish
> Explanation: Brackish water is a mixture of freshwater and saltwater, commonly found in lagoons, estuaries, or coastal areas where rivers meet the sea.
---
9. The ability to do work is referred to as……………………
✔ Answer: energy
> Explanation: Energy is defined as the capacity or ability to do work.
---
10. Plant or animal materials which can be used as a fuel, are known as………………
✔ Answer: biomass
> Explanation: Biomass refers to organic material from plants and animals that can be burned or converted into fuel (like wood, dung, or biofuels).
---
✔ Final Answers:
1.
matter
2.
energy
3.
gas
4.
solid
5.
liquid
6.
