ICS Part 1 Physics English Medium Chapter 4 Online Short Questions Test with Answers

Question # 1

Write down two sources of energy which are renewable

Ans 1: The renewable sources of energy are:
1. Hydroelectric Energy
2. Wind Energy
3. Tides Energy
4. Biomass Energy
5. Sunlight Energy

Question # 2

Name some non- conventional energy sources.

Ans 1: Some of the non-conventional energy sources are:
- Energy from tides
- Energy from waves
- Energy from biomass
- Energy from waste products
- Solar Energy
- Geothermal Energy

Question # 3

Differentiate between geyser and aquifer.

Ans 1: Geyser isa hot spring that discharges steam and hot water, intermittently releasing an explosive column into the air

Aquifer is a layer of rock holding water that allows water to percolate through it with pressure.

Question # 4

What sort of energy is in the following?
(A) Compressed spring (b) Water in high dam

Ans 1: a) A compressed spring has Elastic Potential Energy stored in it.
B) Water in a high dam has Gravitational potential Energy in it.

Question # 5

Define conservative and non-conservative fields?

Ans 1: Conservative field: The field in which work done along a closed path is zero is called conservative field. For Example, Earth's gravitational field

Non-Conservative fields:The field in which work done along a closed path is not zero is called non-conservative field. For Example, field of frictional force.

Question # 6

What is solar constant ? What is its value?

Ans 1: Solar energy at incidence outside the Earth's atmosphere is about 1.4kw m^-2which is referred as solar constant.

Question # 7

How electrical energy can be obtained from sunlight by indirect conversion method?

Ans 1: By using semiconductor devices, the solar cell also called photo voltaic cell: sunlight can be directly converted into electricity. These solar cells are made of silicon wafers. Electron in the silicon gain energy from sunlight to create voltage.Voltage can be increased by increasing the number of solar cells.

Question # 8

What are the essential conditions for conservative field?

Ans 1: For a field to be conservative, energy should be conserved and work should be independent of the path followed.As in case of work done along a path in the gravitational field of earth.

Question # 9

How can we gain energy from tides?

Ans 1: The tides raise the water in the sea roughly twice a day.If the water at the high tides is trapped in a basin by constructing a dam, then it is possible to use this as a source of energy. There dam is filled at high tide and water is released in a controlled way at low tide to drive the turbines and generate electricity.

Question # 10

How energy is obtained from direct combustion and fermentation.

Ans 1: Direct Combustion: It is applied to get energy from waste product commonly known as solid waste and confined it into chamber and ignite it.The heat produced is then used in a boiler to run the turbine of generator

Fermentation: Biofuel such as ethanol is a replacement of gasoline which is obtained by fermentation of biomass using. Enzymes and by decomposition through bacterial action in the absence of air . The rotting of biomass in a closed tank called digester produces biogas which can be piped out to use for cooking and heating.
