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.

Gases and liquids both ____________.

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

  1. can be compressed

  2. have a definite shape

  3. cannot be compressed

  4. have an indefinite shape

  5. have a definite volume

Show answer
Correct Option: A,D

Select the correct answer from the choices given below. The three states of matter are classified on the basis of differences of certain _________.

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

  1. chemical properties

  2. physical properties

  3. physical and chemical properties

  4. none of the above

Show answer
Correct Option: B
Explanation:

The three states of matter are classified on the basis of differences of certain physical properties such as physical existence; solids are physically hard, they have fixed shape and size. Liquids do not have any fixed shape and size, they changed according to the shape of beakers in which they are placed. Gases do not have a fixed shape or volume.

The decreasing order of diffusion is ___________.

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

  1. Gas > Solid > liquid

  2. Liquid > Gas > Solid

  3. Solid > Liquid > Gas

  4. Gas > Liquid > Solid

Show answer
Correct Option: D
Explanation:

The spaces between the particles of gas are more so they can mix into each other very easily. 

Solid has the least intermolecular space, therefore, it is very difficult to mix with another solid. 
On the other hand, liquids have some diffusion ability.

So, the correct option is $D$

Which of the following states of matter are called fluids?

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

  1. Solid, Gas

  2. Solid, Liquid

  3. Liquid, Gas

  4. Solid, Liquid, Gas

Show answer
Correct Option: C
Explanation:

Fluids are the substances that can flow easily so gas and liquid are the states which flow easily.

Arrange the following substances in increasing order of forces of attraction.

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. Sugar, oxygen, water

Show answer
Correct Option: A
Explanation:

The forces of attraction are strongest in solids, followed by liquids and the weakest in gases.oxygen is a gas, water is a liquid and sugar is a crystalline solid. 


So the increasing order of forces of attraction is oxygen $<$ water $<$sugar.

So, the correct option is $A$
