Question

i) Energy can neither be created nor be destroyed. ii) During the charging of lead acid batteries, the chemical energy changes into electrical en- ergy iii) The kinetic energy possessed by a body depends upon its position. 2 of 5​

Answer 1

I don't know the answer but please follow

Answer 2

i. The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

ii. When the electrons move from the cathode to the anode, they increase the chemical potential energy, thus charging the battery; when they move the other direction, they convert this chemical potential energy to electricity in the circuit and discharge the battery.

iii. Kinetic energy of a body depends on the mass of the body as well as its velocity.
