A balloon is filled with helium gas and sealed at room temperature (300 K). It is then placed in sunlight, and the gas inside gets heated. The balloon is flexible and can expand to accommodate the increased pressure. A science student observes that as the temperature increases, the balloon expands and rises higher in the air. The student wants to understand this behavior using the kinetic theory of gases. According to this theory, gas molecules are in continuous random motion, colliding with each other and the container walls. These collisions are responsible for exerting pressure.
