States of Matter

2,682 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 softskills leadership
  1. practical

  2. glass water bottle

  3. immature

  4. steadfast

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Feasible describes something that is capable of being done or achieved, often with practical considerations in mind. Option A captures this meaning perfectly. The other options are unrelated words.

Multiple choice softskills leadership
  1. strip off skin

  2. yielding to another

  3. turn into vapor (steam, gas, fog, etc.)

  4. forerunners

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

To flay literally means to strip off the skin or hide, either of an animal or historically as a form of punishment. Option A correctly defines this term. Option C describes evaporate or vaporize, option B refers to submission, and option D means predecessors or heralds, all unrelated to skin removal.

Multiple choice softskills leadership
  1. temperature

  2. termination

  3. transfer

  4. transition

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

"Transition" correctly describes a change from one state to another, specifically from gas to liquid. Condensation is the phase change process. "Temperature" is a measurement, not a process. "Termination" means ending, and "transfer" means moving something, neither of which accurately describes a phase change.

Multiple choice softskills leadership
  1. hag

  2. change (esp. from good to bad)

  3. (of a person) bold

  4. something that causes a substance in a chemical solution to separate out in solid form

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

"Precipitant" refers to a substance that causes another substance in a chemical solution to precipitate, or separate out in solid form. The other options, such as "hag" or "bold," are completely unrelated to this chemical term.

Multiple choice softskills leadership
  1. less intense

  2. contortions

  3. agent which brings about a chemical change while it remains unaffected and unchanged

  4. untarnished

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Subdue can mean to make less intense, strong, or vivid - to soften or calm. For example, colors can be subdued, or emotions can be subdued. 'Less intense' captures this meaning well.

Multiple choice softskills communication
  1. bubble

  2. suds

  3. yeast

  4. froth

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

'Barm' specifically refers to yeast, especially the foam or froth on fermenting beer. In brewing, barm is the yeast used in fermentation. Options A, B, and D are incorrect - 'bubble', 'suds', and 'froth' refer to the appearance rather than the actual yeast substance.

Multiple choice softskills communication
  1. Melt

  2. Thaw

  3. Weaken

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deliquesce means to melt away or dissolve, particularly becoming liquid. It can mean to melt, thaw, or weaken/dissolve gradually. Therefore 'All of the above' is correct as deliquesce encompasses all these related meanings.

Multiple choice softskills communication
  1. Beer

  2. a sweet wine

  3. Rum

  4. grape juice

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sauterne is a sweet white wine from the Sauternais region of France. It's known for its distinctive sweet flavor profile.

Multiple choice
  1. Gaseous state

  2. Liquid state

  3. Solid state

  4. All have same magnitude

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

This state of matter has relatively low density and viscosity. It also has relatively great expansion and contraction with changes in pressure and temperature. It has the highest magnitude of internal energy among the three states of matter.

Multiple choice
  1. a process where no heat change occurs

  2. an exothermic change

  3. an endothermic change

  4. a process involving both endothermic & exothermic change

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In an endothermic change, energy is absorbed. Heat has to be absorbed in fusion of ice to give water.

Multiple choice
  1. isothermal expansion

  2. adiabatic expansion

  3. adiabatic compression

  4. isothermal compression

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

During adiabatic expansion, there is increase in volume without heat flow, in or out. Inside a refrigerator, due to the isolated system, the adiabatic expansion of refrigerator gases like freon takes place by using the heat from the gas itself. This causes lowering of temperature of the gas, i.e. cooling effect of the refrigerator.
