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 25-minute clock, a question palette and full screen, and your score, the key and the solutions arrive when you submit.

Untimed

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.
  • Open to guests. Normal practice needs no sign-in.

Timed CBT

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

  • A clock that does not pause. 25 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.

Heat and Thermodynamics GK Practice Quiz Level 1 for Beginners

Beginners starting physics for general awareness can use this Heat and Thermodynamics GK Quiz Level 1, the easiest set in the series on Aptitude360. It covers temperature scales, thermometers, conduction, convection and radiation, sea and land breezes, change of state and the basic laws of thermodynamics. Most questions include a written explanation.

What this Heat and Thermodynamics Level 1 quiz covers

  • Normal body temperature, the SI unit of temperature and Celsius, Fahrenheit and kelvin readings
  • Clinical and laboratory thermometers and their ranges
  • Good and poor conductors of heat
  • Conduction in solids, convection in liquids and gases, and radiation from the Sun
  • Sea breeze by day and land breeze by night
  • Latent heat, sublimation, condensation, dry ice and cooling by evaporation
  • Anomalous expansion of water and the zeroth, first and second laws of thermodynamics

Key heat concepts to revise first

  • Radiation is the only mode of heat transfer that needs no medium
  • Light clothes reflect heat in summer, dark clothes absorb it in winter
  • Temperature stays constant during melting or boiling while latent heat is absorbed
  • The first law is a form of conservation of energy; the zeroth law gives the idea of temperature

Study tips for heat GK basics

  • Remember that kelvin readings are found by adding a fixed offset to Celsius values
  • Explain breezes by asking which surface, land or sea, heats and cools faster
  • Pair each law of thermodynamics with one key phrase so options are easy to separate

FAQs about Heat and Thermodynamics – GK Quiz with Answers – Level 1

What are the three modes of heat transfer?
Heat travels by conduction, convection and radiation. Conduction happens mainly in solids, convection in liquids and gases, and radiation needs no medium.
At what temperature are Celsius and Fahrenheit equal?
The two scales show the same reading at minus forty degrees.
What is the first law of thermodynamics?
It is the law of conservation of energy for heat. Heat supplied to a system equals the increase in its internal energy plus the work done by the system.
Why does evaporation cause cooling?
The escaping molecules take latent heat from the liquid and its surroundings. This lowers the temperature of what is left behind.
