Questions Related to substances, objects and energy

Which of the following gas is used in vehicles?

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. L.P.G

  2. C.N.G

  3. Nitrogen

  4. Nitrogen dioxide

Show answer
Correct Option: B
Explanation:

Compressed natural gas is used in vehicles and is a cheap source of fuel.

The kinetic energy of particles is maximum in __________.

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. gas

  2. liquid

  3. solid

  4. Same in all the states

Show answer
Correct Option: A
Explanation:

The kinetic energy of particles is maximum in gas as the particles are free to roam with maximum speed as there is negligible force of attraction between the particle.


Hence the option A is correct.

The gas which is used for cooking at our home is _____________.

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. Oxygen

  2. Nitrogen

  3. L.P.G ( liquefied petroleum gas ) 

  4. C.N.G ( compressed natural gas )

Show answer
Correct Option: C
Explanation:

Liquefied petroleum gas is used for cooking food at the homes.


Hence the option C is correct.

Thermal conduction takes place in ___________.

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. solid, liquid

  2. liquid, gas

  3. gas, solid

  4. solid, liquid, gas

Show answer
Correct Option: D
Explanation:

Thermal conduction takes place in all the states of matter as the energy is transferred through particles so transfer of heat takes place.

The three phases of water (Solid, Liquid, Gas) are:

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. ice, water, steam

  2. water, ice, steam

  3. steam, ice, water

  4. steam, water, ice

Show answer
Correct Option: A
Explanation:

The three phases of water are ice (present in solid state),  water (present in liquid state) and steam (present in the gaseous state).

Which among the following is solid at room temperature?

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. Oxygen

  2. Mercury

  3. Potassium permanganate

  4. Nitrogen

Show answer
Correct Option: C
Explanation:

Oxygen and nitrogen are gases, bromine is liquid at room temperature. So $KMnO _4$ is solid at room temperature.

Particles move randomly in _____________.

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. nitrogen

  2. sugar

  3. ice

  4. water

Show answer
Correct Option: A
Explanation:

Particles move randomly in a gaseous state. Here nitrogen is the only substance which is in a gaseous state.

Which of the following has the highest density?

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. Kerosene

  2. Water

  3. Iron

  4. Wood

Show answer
Correct Option: C
Explanation:

Iron has the highest density as the particles are closely packed and volume occupied is less which makes the density very high.

Arrange the following objects in the order of the intermolecular force of attraction.


( Oxygen, Sugar, Water )

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. Oxygen > Water > Sugar

  2. Sugar > Water > Oxygen

  3. Water > Sugar > Oxygen

  4. None of the above

Show answer
Correct Option: B
Explanation:

The general order of force of attraction is Solid > Liquid > Gas. 


Therefore, the order is Sugar > Water > Oxygen.

A state of matter is characterized by _________.

evs - i substances, objects and energy the states of substances introduction to matter gaseous state

  1. temprature

  2. pressure

  3. phase transition

  4. none of above

Show answer
Correct Option: C
Explanation:

A state of matter is also characterized by phase transitions. A phase transition indicates a change in structure and can be recognized by an abrupt change in properties. A distinct state of matter can be defined as any set of states distinguished from any other set of states by a phase transition.
