Name: Ashrita Suram Date: 11 - 01 - 2020 The air molecules inside heat up and they expand, as the air expands they become less dense than the surrounding outside air. This causes the balloon to fill up and to begin to float in the air. The more heat you add the lighter the balloon becomes. The air will cool, it becomes more dense, takes up less space, and the balloon will begin to sink in the air. 1. Click Pause ( ) when the sailboat starts moving towards the shore.
