Experiment Shows Substance That's Solid, Liquid and Gas...All at Once!
Description:Students in Manchester University undertook an experiment to determine the identity of the fluid in the container through the use of a mass spectrometer*. When vaporising the liquid using a vacuum pump, the students noticed an odd result. They managed to find the triple point of the fluid, which is when a pressure drop in the flask caused the liquid to exist as a solid, liquid and gas all at the same time. *The mass spectrometer is a scientific instrument which can measure the masses and concen(1:00)
