The diagram below shows the temperature dropping from 80°C to 20°C.

Two containers each hold 4 balls. One container has balls with long arrows indicating movement and is labeled 80 degrees Celsius. The other has balls with short arrows and is labeled 20 degrees Celsius. An arrow points from the first to the second container.
Molecules that have longer arrows are moving faster. Which statement describes what is happening in this system?
Molecules vibrate more as temperature decreases.
Temperature is not related to the average kinetic energy of a system.
Kinetic energy decreases as temperature decreases.
There is no change in average kinetic energy between these two systems.

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
