Climate resources - that is, solar radiation, heat, precipitation, and other climatic factors and the number of specific combinations. Solar radiation is the agricultural production of natural energy, plant dry matter of 90 to 95% of the solar system through the use of synthesized photosynthesis. Water is the synthesis of organic materials, but also the lives of all activities necessary for the conditions; land-based water from natural precipitation. Temperature of animals and plants is also an important condition for growth and development, water, fertilizer and light are met, to a certain temperature, many of the plant's growth rate is directly proportional to the temperature and the environment. As a result, the climate resources to a large extent determine the layout of agricultural production, as well as the structure of the high and low yield and quality is good or bad.

So we don't really need to put in a certain amount of heat and change the temperature of the products and the calorimeter and so on.
所以我们实际上并不需要输入,一定的热量,改变生成物,和量热计的温度之类。
And you can find these compressibility factors in tables. If you want to know the compressibility factors for water, for steam, at a certain pressure and temperature, you go to a table and you find it.
各种气体的压缩系数,想知道水或者水蒸气,在某个温度和压强下的,压缩系数,查表就行了,这是实际气体状态方程的。
It's just how much heat is involved when we change the temperature. Now, the products have some heat capacity associated with them right, it takes a certain amount of heat if we make their temperature change, to either put it in or take it away, depending on which direction the temperature is changing.
问题就是当我们改变温度时,有多少热量发生了转移,生成物具有一定的热容,如果我们改变,它们的温度,就要输入或,提取一定的热量,这取决于温度改变的方向。
