3.3 Density, Temperature, and Buoyancy

3.3 Density, Temperature, and Buoyancy. Particles in a substance moves more quickly wen energy is added. This affects the density of the substance. . Different Temperature, Different Density. A substance has a greater density in its solid state than in its liquid state and gas state.

  1. 3.3 Density, Temperature, and Buoyancy Particles in a substance moves more quickly wen energy is added. This affects the density of the substance.

  2. Different Temperature, Different Density A substance has a greater density in its solid state than in its liquid state and gas state.

  3. Except Water

  4. Changing Density By Changing Concentration Dead Sea things that would NOT normally float will float in the salt water. • http://www.youtube.com/watch?NR=1&feature=fvwp&v=aTcyACmiaho Distilled water has a density of one g/ml. If you add salt to this you increase the density of the substance.

  5. Buoyancy Tendency of an object to float when placed in a fluid.

  6. Buoyant Force: • Upward force that a fluid exerts on an object: • opposite to the pull of gravity on an object in a fluid.

  7. Applications of Buoyancy Plimsoll Line: Because of the variation in density in the worlds oceans and rivers, all cargo ships have a plimsoll line painted on their hull. This line shows how heavily a ship can be safely loaded in different water conditions.

  8. Hot Air Balloon As air is heated it becomes less dense than the surrounding air. The buoyant force pushes the balloon up into the air. • http://www.youtube.com/watch?v=VDSYXmvjg6M&feature=related
