    Question

    What happens to the motion of the particles as

    temperature rises?
    A The particles move faster Correct Answer Incorrect Answer
    B The particles move in the same direction Correct Answer Incorrect Answer
    C The particles stay stationary Correct Answer Incorrect Answer
    D The particles slow down Correct Answer Incorrect Answer

    Solution

    As temperature increases, the kinetic energy of particles also increases, causing them to move faster. This phenomenon is explained by the kinetic theory of matter, which states that temperature and particle motion are directly proportional. Key Points: 1. Heat energy increases the velocity of particles. 2. Faster particle movement increases collisions, leading to expansion. 3. In gases, this results in higher pressure. 4. In liquids, faster movement lowers viscosity. 5. In solids, particles vibrate more, potentially weakening bonds. Bee Facts: • (a) Move Faster: Directly linked to an increase in kinetic energy. • (b) Move in the Same Direction: Particles move randomly, not in the same direction. • (c) Stay Stationary: Impossible, as motion increases with temperature. • (d) Slow Down: Only happens when temperature decreases.
