Question: Name the different properties that materials have?
Answer: Materials have different properties like roughness, luster, transparency solubility, flotation, attraction towards a magnet, conduction of heat and conduction of electricity.
Question: What are miscible and immiscible liquids? Give three examples each.
Answer: Liquids that dissolve in water are said to be miscible in water. For example: Alcohol, vinegar lemon juice, honey and glycerin. Liquids that do not dissolve in water are said to be immicible in water. For Eg – Kerosene, coconut oil and diesel.
Question: Name two gases that are soluble in water.
Answer: They are:
- Carbondioxide
- Oxygen
Question: What are magnetic material? Give two examples.
Answer: Material that are attracted to magnet are called magnetic materials. For Eg- Iron, Nickel etc.
Question: How are different materials grouped depending on transparency?
Answer: They are:
- Transparent: Materials that allow all the light to pass through them For Eg – Glass sheet, water etc.
- Translucent: Materials that allow some light to pass through them For Eg – Colored glass, oiled paper etc.
- Opaque: Materials that allow no light to pass through them. For Eg – Wood, stone etc.
Question: Give three characteristics each of solid, liquid and gas.
Answer: Solid:
- Definite shape and volume.
- Cannot be compressed.
- Particles are closely packed.
Liquid:
- Definite volume but no definite shape.
- Can be compressed to small extent.
- Particles are not so closely packed.
Gas:
- No definite shape and land volume.
- Highly compressed.
- Particles are loosely packed.
Thanks for this all of the experiments.
This helped me a lot. So thank you.??
