To explain: The reason for flying of an inflated and untied balloon across the room, if it is released.
Explanation of Solution
Introduction:
Momentum is the product of mass and change of velocity of an object. Momentum is a vector quantity.
When an inflated but untied balloon is released, the air from the balloon will start coming out. This air carries momentum. According to law of conservation of momentum, the balloon will posses the same momentum of air but in opposite direction. Due to this reason, the balloon will fly across the room.
Conclusion:
The momentum of escaping air is in opposite direction to the momentum of the balloon, so the balloon flies in the room.
