Kinetic Theory Of Matter Matter is everything that takes up sapace it means that everything around us is matter, but emotions are not matter.. They also talk about that we can found water in three different ways: liquid, solid or gas. Atoms Atoms are the smallest particle in matter, when two atoms are combined it creates a particle called molecules. Atoms and molecules movement determine the physical state of matter. Matter In Motion Brown made an experiment were he saw that pollen grains in the water move constantly. In honor of him they called the constsant of matter Brownian motion , this idea is called kinetic theory of matter. Temperature And Heat Temperature is the average kinetic energy in an object and heat is the transfer of thermal energy from one object to another because of a difference in temperature. When temperature is high the faster the particles are moving and f the temperature falls particles move slowly but they never stop moving.

Thinking Critically 16. Much discussion has focused on the need to drive more efficient cars and use less electricity. If the law of conservation of  energy is true, why are people concerned about energy usage ? people is using energy for things that are not important . 17. if heat flows in only one direction, how can both hot and cold liquids reach room temperature as they sit on a table?   hot looses heat and goes to the air and the air goes to the cold . 18. think about what happens to jack and jill in the nursery room. what kinds of enrgy are used? how was each energy form used? both, kinetic and potential energy because if they are moving they are using kinetic energy and if they dont is potential energy. 19. compare the 3 temperature scales you learned about. how are they different? how are they similar? in the celsius scale water freezes at    0° and boils at   100 ° farenheit scale water freezes at   32 ° and boils at   212 ° kelvin scale is known as

Conclusion: my conclusion is that it the depends on the size or long of the string . If it is long it will do less swings per minute

One of the big problems in Barranquilla is the trash. We see trash in any place, and that is not good because we are affecting the nature and our city. In my opinion I would design a robot that help with this, I will put te robots in the most affected paces of the city. This robot would have a special sensor that every time it identifies trash it will immediately clean it up and put it in a trash can. In the water it will be a machine like a net and because water is always moving it will catch the trash people leave in the water. Also to stop this people have to put of their part to be better and to care about nature.
