critical thinking 26/08/2017

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? the problem is that the original form of the energy (gasoline) is  now mechanical energy and is of no use once wasteful. to make it usable again it need to be gasoline which takes an extremely long process in nature. 17. if heat flows in only one direction, how can both hot and cold liquids reach room temperature as they sit on a table? the heat from the hot object goes in the air and the air goes to the cold liquid 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? if they are walking they are using kinetic energy but if they are sit down they are using potential energy 19. compare the 3 temperature scales you learned about. how are they different? how are they similar? the Celsius scale is based on 0°. many p

1.Kintic energy is the work necessary to accelerate a body of a given mass from rest to the indicated speed. Once this energy is obtained during acceleration, the body maintains its kinetic energy unless it changes its velocity. 2.Potential energy is the capacity that a body has to perform a job according to the configuration that holds in the system of bodies that exert forces with each other, that is, the potential energy is the energy that is able to generate a job as a consequence of the position of a body. 3.thermal energy is the manifestation of energy in the form of heat. In all materials the atoms that form their molecules are in continuous movement, either moving or vibrating.

1. How does a solid become a liquid? The ice cubes at a temperature of -250 c At this low tempera ture the water mdowles are barely moving and the attraction hold them together easily As the temperatur vises the par hele shake more in all directions, but when the temperahu e reach OC the mdowles begain to break free The crystal s trochu ve be to collapse gain and the soud be comes freely molecules It has aet the holtin pont and beyond the temperatu re increaseses the heat rs entering the sand and breaking the shvehor and forces that hold the molowles then the is all liquid 2.Frezzing  Freezing is as the liquid cools its particles slow down and comes closer together. Attractive Forces basin to trap the par and the crystals be to form The CA in temperature at which this occurs tts called the liquid ing point ee3 is the same temperatu ve as the solid ha point ra constant The tempera tve main while the crystal s re forms after all the lia has become solid the temperature can con
