States of Matter

2,382 Questions

States of matter questions explore physical changes, evaporation, phase transitions, and the properties of liquids and gases. Topics cover density, cryosurgery, heavy water, and electrolytes. This foundational chemistry topic frequently appears in general science sections of SSC and railway exams.

States of Matter Questions

Multiple choice

Using the blend modality, the application of thermolysis causes the lye to:

  1. coagulate

  2. become more porous

  3. become less turbulent

  4. become more caustic
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In the blend modality, the heat from thermolysis increases the chemical reaction rate of the lye (sodium hydroxide) produced by the galvanic current, making it more caustic and effective at destroying the hair follicle.

Multiple choice

Pitta is a combination of what two elements?

  1. air and ether

  2. earth and water

  3. fire and water

  4. air and earth
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In Ayurveda, the Pitta dosha is governed by the elements of fire and water. These elements are responsible for transformation, metabolism, and digestion in the body.

Multiple choice evs sources of water and water cycle groundwater and depletion of water table rain: where does it come from availability and forms of water the water cycle

Which of the following is not naturally occurring form of water?

  1. Solid

  2. Liquid

  3. Vapour

  4. Semi-solid
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Water exists in liquid form upto  $100^0$C , at 100$^0$C it exists as vapour and at 4$^0$C it exists in solid form  as ice. So water exists in all the states or forms except semisolid, jelly state

So, the correct answer is 'Semi-solid'

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

A state of matter is characterized by _________.

  1. temprature

  2. pressure

  3. phase transition

  4. none of above
Reveal answer Fill a bubble to check yourself
C Correct answer
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.

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

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

  1. chemical properties

  2. physical properties

  3. physical and chemical properties

  4. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

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

The decreasing order of diffusion is ___________.

  1. Gas > Solid > liquid

  2. Liquid > Gas > Solid

  3. Solid > Liquid > Gas

  4. Gas > Liquid > Solid
Reveal answer Fill a bubble to check yourself
D Correct answer
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 $D$
