Physical States and Properties States of Matter: Kinetic molecular theory and phase transitions by Anthony Carpi, Ph.D. Reading Quiz Teach with this 1. Different states of matter were first described by the Romans. true false 2. One key point of the Kinetic Molecular Theory is: ice freezes at 0ºC atoms are solid billiard balls atoms possess an energy of motion molecules form solids 3. Intermolecular attractive forces include which of the following? hydrogen ions van der Waals forces Bose-Einstein attraction solids 4. The solid state of matter is unique because all molecular motion stops. true false 5. Liquids have a defined shape and volume have a defined shape but undefined volume have an undefined shape but defined volume have both undefined shape and volume 6. Gases can be compresed because: molecules of a gas are spread out and can be squeezed together molecules of gas can be compresed gases do not contain molecules 7. All molecular motions ceases at absolute zero -273.15ºC both of the above 8. Satyendra Bose predicted absolute zero plasmas that atoms would attain the same quantum-mechanical state at low temperature that solids, liquids, and gases were the only states of matter that could exist 9. Phase transitions occur at precise temperatures. true false 10. Why does temperature remain constant during a phase transition? because no energy is exchanged in the process because frozen substances always keep their surroundings cold because the energy gained or lost is all used by molecules transitioning from one phase to another because Albert Einstein predicted it Score Quiz
