In a room with four corners, Lakshmi and Jamal are standing in opposite corners. Each of them holds a balloon. If they both release their balloons at the same time, and there is a ventilation system that evenly distributes air in the room, but no wind or breeze otherwise, what will happen to the balloons, and why does this happen? Respond very briefly.
The balloons will rise towards the ceiling because the helium or any lighter-than-air gas inside them is less dense than the surrounding air, causing them to float upward due to buoyancy. The absence of wind or breeze means that the balloons will rise vertically if released from different corners and will not move horizontally towards each other. The balloons will go straight up until they hit the ceiling or are otherwise obstructed. The ventilation system, while distributing air evenly, does not create a directional airflow that would affect the balloons' path.
