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 8
A balloon filled with air is left in the sun and expands. Using kinetic particle theory, explain why this happens.
A student notices that the smell of cooking spreads from the kitchen to the living room. Which property of gases does this demonstrate?
A student observes that a drop of ink spreads out faster in hot water than in cold water. Explain why this happens.
A student places a crystal of potassium permanganate in water and observes the color spreading throughout the water. What process is being observed?

Fill in the blank: The change of state from liquid to gas is called __________.
Fill in the blank: The energy that particles have due to their motion is called __________ energy.
Fill in the blank: The process by which a gas changes directly into a solid is called __________.
Fill in the blank: The process of a gas changing into a liquid is called __________.
True or False: Diffusion is the movement of particles from an area of low concentration to an area of high concentration.
True or False: In gases, the forces of attraction between particles are very strong.
True or False: In solids, the particles are closely packed together and vibrate in fixed positions.
True or False: In the kinetic particle theory, temperature is a measure of the average kinetic energy of the particles.
