What a liquid drops quiz should test

Liquid drops hold their shape because surface tension pulls molecules at the surface inward, and that pull makes a free drop as close to a sphere as its volume allows. A quizizz-style quiz on liquid drops works best when it asks you to explain these causes, not just recall the word surface tension.

  • Multiple-choice, true/false and open questions with explanations
  • Questions generated from your own PDFs, slides and notes
  • Free plan includes 3 generations per month, studied in the browser
  • Plus and Pro add exports for PDF, DOCX, Moodle XML and QTI 2.1
Example liquid drops quiz questions with answers
Why does a small liquid drop falling through air take on a nearly spherical shape?Surface tension pulls the liquid toward the shape with the least surface area for its volume, which is a sphere.
True or false: surface tension comes from cohesion between liquid molecules at the surface.True. Surface molecules have fewer neighbors than molecules inside the liquid, so they are pulled inward and form a tight surface film.
Which force makes a water drop stick to a clean glass surface?Adhesion, the attraction between unlike molecules such as water and glass, pulls the water onto the glass.
Why does a water drop bead up on a waxy leaf instead of spreading?Water's cohesion is stronger than its adhesion to wax, so the drop minimizes contact with the leaf and forms a rounded bead.
In the liquid drop model of the nucleus, what does the surface term represent?Nuclear surface energy, which reduces binding because nucleons at the surface have fewer neighbors than those inside.

Questions from your material

Upload PDFs, DOCX files, slides, plain notes or photos of a page. The quiz uses the wording and examples from your own class material.

Explanations for every answer

Each question comes with a short explanation, so a wrong answer teaches you why surface tension or cohesion produced the result.

Exports when you need them

Plus includes PDF and DOCX export. Pro adds QTI 2.1 and Moodle XML for learning management systems.

How it works

Add your notes

Upload a PDF, slides, a DOCX file or paste text from your liquid drops lesson.

Choose the question type

Pick multiple-choice, true/false or open questions, then generate the set.

Practice and review

Answer the questions in the browser, read the explanations and repeat the ones you missed.

Good practice questions connect cohesion, which holds water molecules together, with adhesion, which attaches water to other materials like glass or leaves. Ask yourself why a drop beads on wax and spreads on clean glass, and check whether your answer names the forces involved.

Study the same material in several short sessions. Review the explanations for questions you missed, then try the same idea in a new format, such as a true/false statement or an open question.

Frequently asked questions

Why are liquid drops round when they fall?

Surface tension makes a free drop reduce its surface area for a given volume, and a sphere has the smallest surface area for that volume. Air resistance and gravity can distort larger drops, which is why very big drops flatten.

How do I study surface tension for a test?

Explain the cause of surface tension in your own words, then compare it with adhesion and cohesion using examples like water on glass and water on wax. Practice with questions that ask why, not only what.

Can I export the quiz?

Exports are paid features. Plus includes PDF and DOCX export, and Pro adds QTI 2.1 and Moodle XML export.

Is there a free plan?

Yes. The free plan includes 3 generations per month and studying in the browser, but no exports. You do not need a credit card to start.
