Let’s go step by step to match each sentence with the correct word from the box.
The words in the box are:
- solid
- energy (appears twice — we’ll use it where needed)
- gas
- liquid
- malleability
- matter
- marine
- brackish
- biomass
Now, let’s solve each question:
1. “Things with a mass and occupy space are known as…”
→ That’s the definition of
matter. Everything around us that has weight and takes up space is matter.
2. “Things without a mass and do not occupy space are known as…”
→ This describes
energy. Energy doesn’t have mass or take up space — like light or heat.
3. “A ………… has no definite shape or definite volume.”
→ Gases expand to fill any container — they don’t keep their own shape or volume. So this is
gas.
4. “A ………… has a definite shape a definite volume.”
→ Solids hold their shape and size unless you break them. So this is
solid.
5. “A ………… has a definite volume but no definite shape.”
→ Liquids pour and take the shape of their container, but they don’t shrink or expand much — so they have fixed volume. This is
liquid.
6. “The ability of a metal to be drawn into thin sheet without breaking by hammering or rolling is known as…”
→ That’s called
malleability. Think of gold being hammered into foil.
7. “The water found in seas and oceans is known as ……………water.”
→ Ocean water is salty — that’s called
marine water.
8. “The water found in lagoons is known as………………… water.”
→ Lagoons often mix fresh and salt water — that’s called
brackish water.
9. “The ability to do work is referred to as……………………”
→ In science, that’s the definition of
energy. (We already used one “energy” for #2 — there are two in the box, so we can use the second here.)
10. “Plant or animal materials which can be used as a fuel, are known as………… …. ”
→ These are renewable fuels made from living things — that’s
biomass.
All words are now used correctly.
Final Answer:
1. matter
2. energy
3. gas
4. solid
5. liquid
6. malleability
7. marine
8. brackish
9. energy
10. biomass
