Normal practice, or a Simulated test

Both use the same questions. Normal practice is untimed and needs no account: choose an option and the answer and solution appear at once. The Simulated test is the real computer-based format, with one 30-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

Every question on one page, loading as you scroll. Choose an option and see straight away whether it was right.

  • No timer. Nothing to start and nothing to submit. Stop whenever you like.
  • Answered as you choose. Tap an option and it is marked at once, with the correct answer shown.
  • Solutions in place. The explanation, and the video where one has been added, sit under the question.

The computer-based test format: one clock, a question palette, and a score the moment you submit.

  • A clock that does not pause. 30 minutes from the moment you begin, and the paper is submitted for you when it reaches zero.
  • Question palette. Answered, not answered and marked for review, section by section, as the real interface has it.
  • Full screen, proctored. The test takes over the screen; leaving it three times submits the paper.
  • Answers hidden until you submit. The key, the explanations and your score all arrive together at the end.

About this test

Matter and its States Level 2 Practice Quiz: Evaporation, Mixtures and Heat

Matter and its States Level 2 is a medium-level chemistry GK set that goes past definitions into statement checks, matching and ordering questions. On Aptitude360 it tests evaporation factors, latent heat, the kelvin scale, the difference between solutions, colloids and suspensions, and the choice of separation techniques.

Topics in this Level 2 matter quiz

  • Ordering states of matter by particle spacing and force of attraction
  • Fusion, deposition and sublimation, including substances that do not sublime
  • Arranging Celsius and kelvin temperatures and the precise kelvin value of the ice point
  • Effect of humidity, temperature, surface area and wind on evaporation, such as spreading wet clothes
  • Latent heat of fusion and vaporisation
  • True solutions versus colloids and suspensions, Tyndall effect examples, and matching mixtures to separating funnel, centrifugation and fractional distillation

Concepts that Level 2 questions probe

  • Spotting incorrect claims, for example that boiling occurs only at the surface
  • Odd-one-out reasoning across states, mixtures and pure substances
  • Why solids keep a fixed shape while liquids and gases do not
  • Separation of the gases of air by fractional distillation

How to prepare for medium-level matter questions

  • Revise the reason behind each fact, such as why humidity slows evaporation, rather than memorising lines
  • Convert every temperature to one scale before arranging them in order
  • Keep a two-column list of mixtures and the technique that separates each one

Who should take Level 2

General Awareness aspirants who are comfortable with the basics of matter and want exam-style statement and matching practice in chemistry before moving to harder sets.

FAQs about Matter and its States – GK Quiz with Answers – Level 2

What is the difference between evaporation and boiling?
Evaporation is a surface phenomenon that happens at any temperature below the boiling point. Boiling happens throughout the liquid at a fixed temperature for a given pressure.
What factors affect the rate of evaporation?
Evaporation increases with higher temperature, larger surface area and stronger wind speed. It decreases when humidity in the air increases.
What is the Tyndall effect?
The Tyndall effect is the scattering of a beam of light by colloidal particles, which makes the path of the light visible. Sunlight through a dusty room or a dense forest is a common example.
How do you convert Celsius to kelvin?
Add 273.15 to the Celsius temperature to get the value in kelvin, or 273 for a quick estimate. So the freezing point of water, zero degrees Celsius, is about 273 kelvin.
