Explanation:
According to Charles law, the volume is proportional to temperature at constant pressure. Now, if gas is heated up, it’s temperature rises hence, its volume also rises.
In hot air balloon the air is heated, hence its volume increases so it’s density decreases. As we known that a fluid of less density floats on another object with less density, hence the hot air balloon gets heated up and rises up.
