Questions Related to sources of energy

The energy possessed by the fast moving air or storm is called:

physics sources of energy biomass and biogas biogas conventional sources of energy

  1. hydro energy

  2. kinetic energy

  3. geothermal energy

  4. wind energy

Show answer
Correct Option: D
Explanation:

The energy possessed by the fast moving air or storm is called the wind energy. This energy is used in driving a wind mill.

Biomass can be defined or described as:

physics sources of energy biomass and biogas biogas conventional sources of energy

  1. petroleum

  2. organic matter which can be converted to fuel

  3. inorganic matter which can be converted to fuel

  4. massive living things

Show answer
Correct Option: B
Explanation:

Biomass is organic matter that can be used as energy source, made up of wood, crops and animal waste. It is renewable source of energy.

Choose the correct statement.

physics sources of energy biomass and biogas biogas conventional sources of energy

  1. Biomass energy causes no pollution.

  2. Biomass energy causes heavy pollution.

  3. Biomass energy causes less pollution as compared to conventional sources of energy.

  4. Biomass energy is costly.

Show answer
Correct Option: C
Explanation:

Biomass : Energy comes from living things like wood, animal wastes. Biomass does not produce pollutants like coal and petroleum does as it is completely organic. But burning of it still produce pollutants.

  2. Floating gas holder type

  3. Fixed fuel type

  4. Moving chamber type

Show answer
Correct Option: A,B
Explanation:

Bio gas plant is of two types: fixed dome type and floating gas holder type.

Define biomass.

physics sources of energy biomass and biogas biogas conventional sources of energy

  1. Fossil fuels are also called biomass.

  2. The wastes and dead parts of living beings are called biomass.

  3. The wastes from industrial applications are called biomass.

  4. The wastes and dead parts of living beings buried deep inside the earth are called biomass.

Show answer
Correct Option: B
Explanation:

The waste and dead parts of living beings is called biomass. Wastes and dead parts of living being buried deep inside the earth turns up into fossil fuels after a long time.
