Liquid nitrogen + balloon Follow FizzicsEd 150 Science Experiments: Comments 0 You will need: NOTHING. Do not try this at home or school unless you have formal training. You are also unlikely to have liquid nitrogen at home, or in your school. Copyright Instruction Video Instruction 1 Put on the safety glasses and gloves. Holding the balloon with metal tongs, carefully pour the liquid nitrogen over the surface of the balloon. Watch what happens. 2 Hold balloon up and allow the balloon to drip the liquid nitrogen off it. Watch what happens as the balloon warms up! Blow on it to transfer more heat. 3 Get the Unit of Work on States of Matter here! What are the different states of matter? How does heat affect the size of materials? How does liquid nitrogen affect materials and much more! Includes cross-curricular teaching ideas, student quizzes, a sample marking rubric, scope & sequences & more 4 School science visits since 2004! – Curriculum-linked & award-winning incursions. – Over 40 primary & high school programs to choose from. – Designed by experienced educators. – Over 2 million students reached. – Face to face incursions & online programs available. – Early learning centre visits too! 5 Online courses for teachers & parents – Help students learn how science really works Why Does This Happen? Charles’s Law says that for each 1-degree drop in temperature an ideal gas will drop at the same rate in volume. (i.e. it’s proportional). Liquid nitrogen is – 196 degrees Celsius and causes the air inside the balloon to reduce in volume as it cools very quickly. As the air inside the balloon drops in volume, it exerts less pressure on the inside of the balloon. The air outside of the balloon has much higher pressure compared to the cold air inside the balloon… this pressure difference allows high-pressure air outside of the balloon to ‘squash’ the balloon. When you blow on the ‘squashed balloon’, the air inside warms up again and in doing so increases in pressure and is able to get bigger again! Variables to test Does this work with ice?
