化学能转化成电能的实验设计

Experimental Design of Conversion of Chemical Energy into Electrical Energy

以常见的铜锌原电池反应为例,设计了一组对比实验装置,即化学反应装置与原电池装置。以化学反应装置中的能量变化为依据,展示了化学反应中释放出的能量具体形式为"热"与"功";通过与原电池装置的比较,证明原电池实验装置中的"热"转化为了电能。

In this paper, a set of contrast experimental device, i.e. chemical reaction device and primary battery device, was designed by taking the common copper-zinc galvanic cell reaction as an example. The specific forms of energy released in the chemical reaction are shown as "heat"and "work"based on the energy change in the chemical reaction device. Compared with the primary battery device, it is proved that the "heat"in the primary battery converts into electrical energy.
