That's the important message, delta H of formation of the products, minus delta H of formation of the reactants.
去反应物的生成焓,这,是个重要的信息,生成物的生成焓,减去反应物的生成焓。
That's amazing, you can get atoms to smash atoms and create a chain reaction and create power-- that's a pretty amazing invention.
很惊人,你可以利用原子去做加速粒子,并产生连锁反应,然后创造能量-,那是个十分惊人的发明。
It's a state function. If we know the enthalpy of the products minus the enthalpy of the reactants, right. It's a state function.
如果我们知道生成物的焓减,去反应物的焓的值,它是个态函数,原则上我们可以做到。
Or you get a cold, the cold virus takes hold, the viruses start replicating inside of you and it takes some time for immune system to gear up to eliminate it, so we're used to thinking about responses that take some time.
或者你得了感冒,感冒病毒扎根在你的身体中,病毒开始在你体内复制,免疫系统需要一定时间做好准备去消灭它,所以我们曾认为免疫反应需要一定时间
Anybody have an idea? What's the one function of state? I'm the system, the rest are the surrounding. What's the one function of state that's constant when I'm doing all my chemical reactions to move my arms around?
态函数又是什么呢?,我是一个系统,其余的是周围的环境,那么当我在做所有的化学反应,去四处移动我的手臂的时候,什么量是常数?
