Volume and pressure are held constant why does the hot air balloon rise and fall?
Although volume and pressure are held constant, some of the gas escapes from the bottom of the balloon, thus decreasing the mass of the gas in the balloon. If mass is decreased, then density is also decreased because density=mass/volume. Such a decrease in density of the balloon causes it rise.
How does heat make paper spiral spin?
Heat causes air to rise by convection. As the air rises it applies pressure to the underside of the blades. This causes the paper spiral to spin.
How does heat lead to expansion?
