Chapter 3 Summary
Heat if a form of energy that all other forms of energy primarily evolve around. Whenever one form of energy transforms from one to another some of this energy is lost or gained in the form of heat. Restoring lost heat molecules and atoms needs energy so in the end you lose instead of gaining energy. Heat travels from areas of high temperature to areas of lower temperatures. Confusion of temperature and heat is a common. Heat is energy, while temperature is a way for humans to estimate how hot something is. Heat is energy held within objects caused by the vibration of atoms and particles inside of the object itself. The more the particles inside of an object move the hotter the object and the slower the particles move the cooler the objects are. When particles slow down to its fullest potential they reach the lowest possible temperature, which is absolute zero. The reason to why some objects feel cooler than others although they are all at room temperature is due to certain objects being better conductors and insulators of heat.
Chapter 4 Summary
Gravity is inevitable, no matter how many times you try jumping off a cliff you will fall towards the Earth and this is due to the Earth’s gravity lying in the center of the Earth. This causes objects to be pulled down to Earth. All objects have a center of gravity no matter how complicated the shape. Particles have more force below them than above them and this is why the Earth has one point that everything attracted to which is its center of gravity. When hot air rises through an atmosphere it also causes it to cool off the air. When one thinks of hot air rising they often neglect to think of it rising through the air. Warmer, lighter air moves through the heavier, cooler air because gravity pulls down on the cool air more strongly than the warm air. Although, most do not know all the important roles gravity plays, it is vital to life on
