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 11
A gas is compressed at constant temperature. What happens to the distance between its particles?
A sealed syringe contains air. When the plunger is pushed in, what happens to the pressure inside the syringe?
A student observes that a drop of ink spreads out in water. Which property of particles does this demonstrate?
Describe the arrangement and movement of particles in a liquid.
Describe the difference in particle arrangement between a solid and a gas.
Describe what happens to the movement of particles as a liquid is cooled to its freezing point.
During which change of state do particles lose energy and move closer together?
Explain why a gas fills the entire volume of its container.
Explain why gases can be compressed easily but solids cannot.
Explain why increasing the temperature of a gas at constant volume increases its pressure.
Explain why solids have a definite shape and volume.
State the three main states of matter according to the kinetic particle theory.
Which state of matter has particles with the least amount of kinetic energy?
Which state of matter has the highest kinetic energy of particles?
A sample of gas is cooled at constant volume. According to the kinetic particle theory, what happens to the pressure exerted by the gas? Explain your answer.
A sealed container holds an equal mass of oxygen and hydrogen gas at the same temperature and pressure. According to the kinetic particle theory, which gas has a higher average speed of particles? Explain your answer.
A student places a crystal of potassium permanganate at the bottom of a beaker of still water. After some time, the entire solution turns purple. Using the kinetic particle theory, explain this observation.
Describe how the kinetic particle theory explains the process of evaporation and why it occurs more rapidly at higher temperatures.
Explain why the rate of diffusion of ammonia gas is higher than that of chlorine gas at the same temperature, using the kinetic particle theory.
Explain, using the kinetic particle theory, why increasing the pressure on a gas at constant temperature causes its volume to decrease.
