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 35-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. 35 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 Quiz Level 3: Laws, Latent Heat and Scales

This Level 3 Heat and Thermodynamics GK quiz on Aptitude360 builds deeper understanding of how heat moves, how matter changes state and how temperature is measured. It covers the laws of thermodynamics, latent heat, coastal breezes, the unusual behaviour of water and conversions between Celsius, kelvin and Fahrenheit. Every question has a written solution.

Topics covered in this Heat and Thermodynamics set

  • Zeroth, first and second laws of thermodynamics and what each one states
  • Latent heat, melting, boiling and sublimation of dry ice
  • Conduction, convection and radiation, with good and poor conductors
  • Sea breeze and land breeze, and the day-to-night sequence at a seashore
  • Anomalous expansion of water and its point of maximum density
  • Clinical thermometer range and laboratory thermometer use, and conversions between Celsius, kelvin and Fahrenheit, including the point where Celsius and Fahrenheit readings are equal

Key thermal physics concepts to revise

  • Why temperature stays constant during a change of state even though heat is supplied
  • Thermal equilibrium as the basis of temperature measurement
  • The direction in which heat flows on its own between hot and cold bodies
  • Fixed points of water on all three temperature scales
  • Equal size of one Celsius degree and one kelvin

Revision tips for thermodynamics GK questions

  • Make one table listing the freezing point, boiling point and body temperature on all three scales
  • Link each law of thermodynamics to one everyday example so that match-the-list items become quick
  • For breeze questions, remember that land heats and cools faster than the sea
  • Read every statement in multi-statement items, since a single word such as colder or hotter changes the answer

Who should take this Level 3 heat quiz

General Awareness aspirants who have finished the basics of heat and want harder statement-based and matching practice will gain the most from this set. Students in Chandigarh and elsewhere can use it to revise physics GK before competitive exams.

FAQs about Heat and Thermodynamics – GK Quiz with Answers – Level 3

What is the zeroth law of thermodynamics?
It states that if two systems are each in thermal equilibrium with a third system, they are in thermal equilibrium with each other. This law is the basis for measuring temperature with a thermometer.
What is latent heat in simple words?
Latent heat is the heat absorbed or released when a substance changes its state, such as from ice to water, without any change in its temperature.
Why does a sea breeze blow during the day?
During the day, land heats up faster than the sea, so the warm air over land rises. Cooler air from the sea moves in to take its place, which creates the sea breeze.
What does the second law of thermodynamics say about heat flow?
It says that heat does not flow by itself from a colder body to a hotter body. Work must be done, as in a refrigerator, to move heat in that direction.
