Frozen Balloon

The video explores how the volume of a gas changes with temperature under constant pressure. Using a helium-filled balloon and liquid nitrogen, the experiment demonstrates that cooling the gas causes it to contract, while warming it causes expansion. This principle is analogous to bread baking, where gas bubbles expand with heat, making the bread rise. The video highlights the relationship between gas volume and temperature, emphasizing that volume increases with heat if pressure remains constant.

What happens to the volume of a helium balloon when it is placed in liquid nitrogen?
