What kind of energy is stored energy? Energy: In basic terms, 'energy' is defined as the ability to do work. Lifting a box from the floor to the table is work because you must expend energy to move the box from one place to another. ...
772.The future home will use integrated sensors to tell when you leave home each morning, and then go into an energy-efficient mode all by itself. 未来的住宅将使用集成传感器来感应你每天早晨何时出门,然后自动进入节能模式...

The energy released by this enormous collision was equivalent to hundreds of billions of hydrogen bombs. The impact is so violent that the impacting object is destroyed.这次巨大碰撞释放的能量相当于数千亿颗氢弹。撞击如此猛烈以致于撞击物都被摧毁了。The surface of the Earth is completely liquefied, a...
People of all ages can participate in this kind of exercise, which can help get rid of garbage and make our neighbourhood clean and beautiful. More than that, what is the most important is that it makes the public aware of environmental ...
so fire is considered pure energy? and that energy is a direct reaction of different elements mixing with one another? although i never had an official college course in chemistry, i remember going to an education summer camp and learning in a brief amount of time a little bit about the ta...
在火中,氧分子将更大的分子氧化成二氧化碳和水蒸汽,火中的所有光和热都来自于含碳的大分子同氧气的结合。
小题1:根据空白处前后句“Inspiration is a powerful force.”“Here are several ways to light the fire and inspire you to take action:Inspiration is a powerful force.”可知,这里谈论的是inspiration,F项符合情境,故选F。小题2:根据“Be decisive... Take action and test your results.”可知,本段...
The law of conservation of energy states that energy can never be created or destroyed, it is only transformed between different types. There are many types of energy including: kinetic, gravitational potential energy, chemical energy, thermal energy and more. ...
This kind of energy change is central to most chemical reactions. All molecules try to achieve the lowest possible energy state in order to gain stability. During combustion, the atoms lose a lot of energy, so the de-excitation of electrons occurs. ...
