Interactive States of Matter Class 5 Worksheet for Beginners ... - Free Printable

Problem: Solve the worksheet on "States of Matter"

#### 1. Fill in the blanks
We need to fill in the blanks based on our understanding of matter and its properties.

a. A ______ has a definite shape and definite volume.
- Answer: Solid
- Explanation: Solids have a fixed shape and volume because their particles are closely packed and vibrate in place.

b. Anything that has weight and occupies space is called ______.
- Answer: Matter
- Explanation: Matter is anything that has mass and occupies space. It can exist in different states (solid, liquid, gas).

c. Matter is made up of small particles called ______.
- Answer: Atoms/Molecules
- Explanation: Matter is composed of tiny building blocks called atoms or molecules, depending on the context.

d. The change of paper into ash is an example of ______.
- Answer: Chemical change
- Explanation: When paper burns and turns into ash, new substances are formed, which is characteristic of a chemical change.

#### 2. Who am I?
We need to identify the substance or concept based on the given clues.

a. I am a liquid and soluble in water.
- Answer: Water
- Explanation: Water is a liquid and is highly soluble in itself.

b. I condense to form water on cooling.
- Answer: Water vapor
- Explanation: Water vapor is the gaseous state of water. When it cools, it condenses back into liquid water.

c. I am building blocks of matter.
- Answer: Atoms/Molecules
- Explanation: Atoms and molecules are the fundamental building blocks of all matter.

#### 3. Tick (√) the correct word
We need to choose the correct term from the given options.

a. Alcohol and glycerine are (immiscible / miscible) liquids.
- Answer: Miscible
- Explanation: Alcohol and glycerine are completely soluble in each other, meaning they are miscible liquids.

b. Atoms of (different / same) kinds combine and give rise to compounds.
- Answer: Different
- Explanation: Compounds are formed when atoms of different elements combine chemically.

c. In (solid / liquid) molecules are loosely packed.
- Answer: Liquid
- Explanation: In liquids, molecules are more loosely packed compared to solids but more tightly packed than gases.

#### 4. Define
We need to define the terms provided.

a. Chemical change
- Definition: A chemical change is a process in which one or more substances are transformed into new substances with different chemical properties. Examples include burning, rusting, and cooking.

b. Matter
- Definition: Matter is anything that has mass and occupies space. It exists in three primary states: solid, liquid, and gas.

c. Physical change
- Definition: A physical change is a change in the form or appearance of a substance without altering its chemical composition. Examples include melting ice, boiling water, and tearing paper.
