Question
What happens to the motion of the particles as
temperature rises?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.
