Storyboard Text

  • The Law of Conservation of Mass states that mass can not be created nor destroyed.
  • Today we are talking about Conservation of mass.
  • Imagine you are lighting up your gas grill for the first summer barbecue. 
  • Close your eyes and imagine.....
  • The propane from your heavy gas tank reacts with the oxygen in the air, generating a hot blue flame. The products of this reaction are water vapor and carbon dioxide gas.
  • Keep your eyes close!
  • If you were to capture all of the water vapor and carbon dioxide produced as you grill your food, the total mass would equal that of the propane and the oxygen that went into the reaction,
  • If 100 grams of propane and oxygen are used,then 100 grams of water vapor and cardon dioxide are produced.
  • That's it for today's lesson Have a great day!
