Answer 1

Explanation:

1. Bhopal gas tragedy was one of the first major industrial disasters that occurred from an accident. The plant had release 42 tonnes of a toxic gas killing more than 15000 people. People were running on streets dying and vomiting. The toxic gas has affected trees and animals too.
2. Acid rain is caused when the oxides of nitrogen and sulphur are precipitated from the rain water. These oxides are present in the upper atmosphere and when rain falls these oxides get dissolved in rain water and forms nitric acid and sulphuric acid thus makes it acidic. This type of rain is called acid rain.
3. Exhaustible: petroleum, coal, natural gas, forests, minerals, wate Inexhaustible: wind, sunlight.
4. An ideal fuel should have the following properties:High calorific value. Moderate ignition temperature. Low moisture content. Low NOn combustible matter.
5. The basic methods for extinguishing a fire are to suffocate it by ensuring that it cannot have access to oxygen, to cool it with a liquid such as water which reduces the heat or finally to remove the fuel or oxygen source, effectively removing one of the three elements of fire.There are four classes of fire extinguishers – A, B, C and D – and each class can put out a different type of fire. Multipurpose extinguishers can be used on different types of fires and will be labeled with more than one class, like A-B, B-C or A-B-C.
6. Nonrenewable energy resources, like coal, nuclear, oil, and natural gas, are available in limited supplies. This is usually due to the long time it takes for them to be replenished. Renewable resources are replenished naturally and over relatively short periods .Fossil fuels.Crude Oil.,etc
7. The outer zone is blue, the middle zone is yellow and the inner zone is black.
