Grade 10 · Physics
This quiz helps revise “Molecular physics and thermodynamics” in Physics for grade 10. It has 25 questions in five categories: Molecular motion, Gas laws, Vapour and liquids, Internal energy, Heat engines. Questions get harder as the points go up, from 100 to 500.
The 100- and 200-point questions are open here. The rest show only their first words, and there are no answers: all of that is in the game itself.
