Global Issues: Ozone Depletion, Global Warming and Acid Rain

Introduction

Air pollution is exerting increasing impact on the environment. Humans have been altering the chemistry of the atmosphere on a global scale. These changes may:
Modify the global climate
Threaten the health of human beings
Create many environmental problems such as
Acid rain
Depletion of ozone layer
Global warming
Seriously upset the global ecosystem

What is ozone depletion?

Ozone is a highly reactive gas comprising ....etc

Nowadays maintenance-free lead-acidbatteries are common in vehicles,inverters, and UPS systems. If thebattery is left in a poor state of charge, itsuseful life is shortened. It also reduces thecapacity and rechargeability of the battery.For older types of batteries, a hygrometercan be used to check the specific gravityof the acid, which, in turn, indicates thecharge condition of the battery. However,you cannot use a hygrometer for sealedtypemaintenance-free batteries. The onlyway to know their charge level is by checkingt ....etc

The Lead Acid Battery
Lead-acid batteries, invented in 1859 by French physicist Gaston Planté, are the oldest type of rechargeable battery. Despite having a very low energy-to-weight ratio and a low energy-to-volume ratio, their ability to supply high surge currents means that the cells maintain a relatively large power-to-weight ratio. These features, along with their low cost, make them attractive for use in motor vehicles to provide the high current required by automobile starter motors.
