* Kinetic Molecular Theory: This theory states that the temperature of a substance is directly proportional to the average kinetic energy of its particles. Kinetic energy is the energy of motion.
* Increased Temperature, Increased Kinetic Energy: As the temperature rises, the air particles absorb more thermal energy. This increased energy translates into faster movement of the particles.
* Faster Particles, Higher Pressure: The faster-moving particles collide with the inside of the balloon more frequently and with greater force. This increased pressure pushes the balloon outward, making it expand.
In summary:
* Higher temperature ➡️ Higher kinetic energy of air particles ➡️ Faster moving particles ➡️ Higher pressure inside the balloon ➡️ Balloon expands.
