Kinetic Particle Theory of Matter
Chemistry ⇒ States of Matter
Kinetic Particle Theory of Matter starts at 7 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Kinetic Particle Theory of Matter.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 9
A sealed syringe contains air. When the plunger is pushed in, the volume decreases. Explain this observation using the kinetic particle theory.
Describe how the kinetic particle theory explains the expansion of substances when heated.
Describe the changes in particle movement and arrangement when a gas condenses to form a liquid.
Describe what happens to the arrangement and movement of particles during melting.
Describe what happens to the forces of attraction between particles as a substance changes from solid to liquid.
