Gas Laws

Lusaac's Law - Lusaac's law states that at a constant volume, pressure and temperature are directly related. I think the bottle with thermometer in it experiment is a good example of this because when we would increase the pressure the temperature would go up. When we decreased the pressure the temperature would go down.

Charles' Law - Charles' law states that at a constant pressure, volume and temperature are directly related. I think the balloon and heater experiment shows this law very well. When the balloon was put in front of heater, the molecules heated up and started to move faster. The balloon started to expend and become less dense so it floated higher in the air. When it started to cool down the molecules slowed down, shrunk, and became less dense. Causing the balloon to fall back to the floor. A real life example of this is putting a balloon in the freezer and seeing it shink.

Boyle's Law - Boyle's law states that at a constant temperature, pressure and volume are indirectly related. I think the straw popper experiment shows this law. When I twisted the straw, the volume started to decrease while the pressure increased. When I flicked the pocket of air the volume increased while the pressure decreased causing the popping noise. I do this experiment a lot in real life at mcdonalds.
