The reason why expanding gas rises is because of the heat that causes the molecules of the substance to move farther apart, making the substance occupy more space. The opposite effect is caused by a loss of heat.

Carbon dioxide
Yeast converts sugar into the gas carbon dioxide. This causes the dough to expand or rise, as gas forms pockets or bubbles.
Yes, it respires and releases carbon dioxide; this causes bread to rise.
Yes, the random motion of gas particles causes them to exert pressure on the walls of the container, leading to the gas expanding to fill the available space. This is known as diffusion, where gas molecules spread out to achieve maximum entropy within the container.
Carbon dioxide is the gas produced by yeast cells during fermentation that causes bread dough to rise through the process of leavening. This gas gets trapped in the dough, creating air pockets that expand and make the bread rise.
Brownies rise in the oven due to the leavening agents, such as baking powder or baking soda, that create gas bubbles in the batter. The heat from the oven causes these gas bubbles to expand, making the brownies rise and become light and fluffy.
Your juice bottle is expanding because of a build-up of gas inside the bottle, which causes the pressure to increase and the bottle to expand. This can happen due to fermentation or other chemical reactions occurring in the juice.
Baking soda (sodium bicarbonate) will evolve carbon dioxide gas when heated. This gas causes baked goods to rise and become fluffy.
The process that causes water on Earth's surface to change to gas and rise into the atmosphere is called evaporation. This occurs when the sun's heat energy causes water molecules to gain enough energy to break free from the liquid's surface and enter the air as water vapor.
The gas inside the bubble is less dense than the surrounding water
Your lungs expanding and closing.
