Q6. What is all otropy? Give two examples.

Answer: The property due to which a chemical element exists in two or more different forms having similar chemical properties is called all o trophy. These forms are called all o tropes.

Carbon and Phosphorus are the examples to exhibit this property.

Q8. How would you reduce green house effect?

Answer:

Reduction of green house effect: The following remedies can be taken to reduce green house effect:

1. The most obvious is to reduce the amount of fossil fuel burning, either through energy conservation or by introduction of alternative energy sources.

2. It might be possible to filter CO2 from power station emissions, convert it to other chemical forms and dispose it off in places other than the atmosphere, such as oceans.

3. Planting more trees may reduce the CO2 content in the atmosphere. So reforestation programmes have been launched.

4. The society should accept the changing climate.

Q9. What is the reason that we see a pencil broken when half dipped in water?

Answer: This is due to refraction of light. The rays coming from the lower points of the pencil bend away from the normal at the surface of water and we see raised pencil dipped in water. So it looks broken or bent.

Q10. What is angle of deviation?

Answer: The angle which incident ray makes with the emergent ray is called Angle of deviation i.e. the angle between incident ray and the emergent ray is called angle of deviation.
