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 12
A gas is compressed at constant temperature. What happens to the average kinetic energy of its particles?
A sealed syringe contains air. When the plunger is pushed in, the volume of air decreases. Explain this observation using the kinetic particle theory.
A student observes that a drop of ink spreads out in water until the color is evenly distributed. Explain this observation using the kinetic particle theory.
A student places a crystal of potassium permanganate in water and observes the color spreading throughout the water. What process is being observed?
Describe how the kinetic particle theory accounts for the expansion of substances when heated.
Describe the arrangement and movement of particles in a liquid.
Describe the changes in particle arrangement and movement during the freezing of a liquid.
Describe the difference in particle movement between boiling and evaporation.
Describe what happens to the movement of particles as a gas is cooled to become a liquid.
Explain why a liquid takes the shape of its container but a solid does not.
Explain why diffusion occurs faster in gases than in liquids.
Explain why gases have neither a definite shape nor a definite volume.
Explain why increasing the temperature of a gas at constant volume increases its pressure.
Explain why solids have a definite shape and volume according to the kinetic particle theory.
When a solid is heated, its particles gain energy and begin to move more vigorously. What is the name of the process when the solid turns into a liquid?
Which state of matter has the highest kinetic energy of its particles?
Which state of matter has the strongest intermolecular forces?
A liquid and a gas are both at the same temperature. Explain, using the kinetic particle theory, why the gas can expand to fill its container while the liquid cannot.
A sample of gas is heated at constant pressure. Describe, using the kinetic particle theory, what happens to the volume of the gas and why.
A sealed container holds an ideal gas at a constant temperature. If the volume of the container is halved, explain in detail how the kinetic particle theory accounts for the observed change in pressure.
