PROPERTIES • From this following description, determine all the properties of hydrogen that fit each of the following classifications: Extensive Intensive Chemical Physical
PROPERTIES A sample of hydrogen has a volume of 1.2 liters. The sample is a colorless, odorless gas. When a sample is added to a sample of oxygen and a spark is struck, an explosion occurs and (if the container doesn’t break) water can be found as a product of the explosion.
CHEMICAL or PHYSICAL CHANGES? • Making an iron bar into a magnet • Burning a sample of carbon • Ice cubes “shrink” over time in the freezer • Steel forms red rust when exposed to air • Sugar dissolves in water
CHEMICAL or PHYSICAL CHANGES? • Heating a sample of ice until it melts • Grape juice ferments into wine • Tearing a sheet of paper into tiny pieces • Fusion of hydrogen to helium in the sun
