Place a 400 ml beaker, half-filled with water, on a bot plate and let it reach boiling. Set the hot plate on low. Place a pinch clamp on the knot end of the balloon and place the balloon on the top of the beaker so that the pinch clamp sits inside the beaker but does not touch the water. What happens to the balloon after it has been on the beaker for 5 minutes? Explain your observation. Predict what would happen if you heated the balloon to an even higher temperature What do you think is happening on the microscopic scale (atomic level)? After heating the gas, did the density of the gas in the balloon change? Explain your answer Remove the balloon from the beaker and place it in an ice bath. Explain what happens.
