Let's solve the worksheet step by step.
---
Q.1: Use the words in the box to label the common states of matter.
Words to use:
- Liquid
- Gas
- Solid
Now, look at the three diagrams:
1.
First image (left):
- Shows cube-shaped objects with particles tightly packed in a fixed arrangement.
- This represents a
solid because solids have a definite shape and volume, and particles are closely packed.
✔ Label:
Solid
2.
Second image (middle):
- Shows particles in a container, not tightly packed but still close together, filling the bottom of the container.
- The particles can flow and take the shape of the container, but they maintain a fixed volume.
- This is a
liquid.
✔ Label:
Liquid
3.
Third image (right):
- Particles are spread out and moving freely, forming an irregular shape that expands to fill the space.
- This represents a
gas, which has no fixed shape or volume and expands to fill its container.
✔ Label:
Gas

Liquid
-
Gas

Q.2: Write T or True if the statement is true; write F or False if the statement is false.
Let’s evaluate each one:
1.
Matter is anything that has mass and takes up space.
✔ True – This is the definition of matter.
2.
Volume is the amount of space an object takes up.
✔ True – Volume refers to the space occupied by an object.
3.
Gases are not matter because most are invisible.
✘ False – Even though gases are often invisible, they still have mass and take up space, so they
are matter.
4.
The term “fluids” collectively refers to liquids and gases.
✔ True – Fluids include both liquids and gases because they can flow and do not have a fixed shape.
5.
Particles in the solid state are not in motion.
✘ False – Particles in solids
do vibrate in place, even though they are tightly packed. They are not completely stationary.
