5. Molten Rock below the surface of the earth is called

1. Basalt

10. The depletion in ozone layer is caused by

1. Nitrous oxide

2. Carbon dioxide

3. Chlorofluorocarbons

4. Methane

Ans : 3

Chlorofluorocarbons (CFCs), also known as Freon, cause the breakdown of the ozone layer that protects the earth from the sun's ultraviolet (UV) radiation.

In the upper atmosphere, the UV induced breakdown of CFCs releases free, highly reactive chlorine and bromine atoms that lead to the breakdown of the stratosphere ozone layer.

Owing to ozone depletion in the upper atmosphere, CFCs have been phased out under the Montreal Protocol of 1987.

13. Phosphorus is kept in water because

1. It's ignition temperature is very high

2. It's ignition temperature is very low

3. It's critical temperature is high

4. It's critical temperature is low

Ans : 2

The allotropic form of phosphorus (white phosphorus) is less stable and therefore highly reactive because of angular strain in P4 molecule where the angles are only 60°.

Having very low ignition temprature, it readily catches fire in air to give dense white fumes of P4O10.

So it is kept in water to avoid oxidation by the oxygen present in air.

14. The unit of measurement of noise is

1. Decibel

2. Hertz

3. Amplifier

4. Acoustics

Ans : 1

The decible (dB) is the unit used to measure the intensity of sound or noise level.

It is given in terms of a logarithmic function of a ratio of power intensities.

One decible is one tenth of one bel, named in honour of Alexander Graham Bell who was the inventor of the telephone and phonograph.

15. The commonly used coolant in refrigerators is

1. Ammonia

2. Nitrogen

3. Freon

4. Oxygen

Ans : 3

Modern refrigerators usually use a refrigerant called HFC - 134a (1,1,1,2-Tetrafluoro ethane), which does not deplete the ozone layer, instead of Freon.

Freon used to be the most common refrigerant till the 1980s; however, its use has declined since the 1990s because it comes under Chlorofluorocarbon (CFC).

Ammonia was also used a common refrigerant in old refrigerators.

However,Freon still remains the most commonly used refrigerant

Hydrochlorofluorocarbon (HCFC), is a type of refrigerator coolant used in newer refrigerator models.

The types used today include HFC-134a, HCFC-142b & HCFC- 22.

4. Inbuilt Circuit

Ans : 3

IC stands for Integrated Circuit.

It is a set of electronic circuits on one small plate ("chip") of semiconductor material, normally silicon.

Also known as chip or microchip, ICs are the heart and brains of most circuits and are a keystone of modern electronics.

20. Sea water is saltier than rainwater because

1. Sea animals are salt producing

2. The air around the sea is saltish

3. Rivers wash away salts from earth and pour them into the sea

4. See beds have salt produce producing mines

Ans : 3

Seawater is salty because rain water dissolves the salt minerals found in soil and rock as it travels through rivers and streams enroute to the sea.

The rain that falls on the land contains some dissolved carbon dioxide from the surrounding air.

This cause the rainwater to be slightly acidic due to carbonic acid.

The rain physically erodes the rock and the acids chemically break down the the rocks and carries salts and minerals along in a dissolved state as ions.

The ions in the runoff are carried to the streams and rivers and then to the ocean which makes them salty.
