11、ned about energy. Do you know that HEAT is a form of ENERGY? Yep, this form of energy acts on everything. And, were going to look at a few experiments to learn how this form of energy acts and why we need to know all about it.The heat energy of something is decided by how active its atoms(原子)and mol
12、ecules(分子)are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler objects molecules and atoms will be less excited and show less movement. When these guys are in the excited state, they take up a lot of space because theyre moving around so fast. When the ato
13、ms and molecules settle down, or cool down, they take up less space.If a HOT high-energy atom comes into contact with a cool low-energy atom, the excited atom will loose some of its energy to the cool atom. The two atoms will reach an energy level thats between where they each started out. That leve
14、l is called Thermal Equilibrium. Experiment: If you have a cup of really hot chocolate and want to cool it down, you may put an ice cube in the cup.
