The P&L statement is synonymous with the income statement. The profit & loss account provides information about an enterprise's income and expenses which result in net profit or net loss. It helps a businessman to evaluate the performance of an enterprise and provides a basis for forecasting future performance.

There are four major types (or “ranks”) of coal. Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever denser, drier, more carbon rich, and harder material. The four ranks are:
- Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter.
- Bituminous: Bituminous coal is a middle rank coal between subbituminous and anthracite. Bituminous usually has a high heating (Btu) value and is the most common type of coal used in electricity generation in the United States. Bituminous coal appears shiny and smooth when you first see it, but look closer and you may see it has layers.
- Subbituminous: Subbituminous coal is black in color and dull (not shiny), and has a higher heating value than lignite.
- Lignite: Lignite coal, aka brown coal, is the lowest grade coal with the least concentration of carbon.

2Y+5/3=26/3-Y
2y + y = 26/3 - 5/3
3y = (26 - 5)/3
3y = 21/3
3y = 7
y = 7/3

A computer is a machine that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming. Modern computers have the ability to follow generalized sets of operations, called programs. These programs enable computers to perform an extremely wide range of tasks. Mainframes, desktop and laptop computers, tablets, and smartphones are some of the different types of computers.

The formation of fossil fuels is a very slow process, it takes millions of years. Hence, the amount of resources available for use is limited and is being exhausted by human activities like industrialization, rapid growth, etc. Thus, fossil fuels are exhaustible natural resources. The process of formation of fossil fuels requires millions of years. Dead vegetation and animals that get buried deep inside the earth require high temperature and pressure for the formation of fossil fuels, which cannot be done in the laboratory.

ANSWER
1. It should possess high calorific value.
2. It should have proper ignition temperature. The ignition temperature of the fuel should neither be too low nor too high.
3. It should not produce poisonous products during combustion. In other words, it should not cause pollution o combustion.
4. It should have moderate rate of combustion.
5. Combustion should be easily controllable i.e., combustion of fuel should be easy to start or stop as and when required.
6. It should not leave behind much ash on combustion.
7. It should be easily available in plenty.
8. It should have low moisture content.

Flame is a region where combustion or burning of a gaseous substance takes place. Only the solid or liquids which form gases when heated burn with a flame. Some of the substances which burn by producing flames are LPG, biogas, candle wax, camphor, magnesium and mustard oil.
Charcoal and coal does not burn by producing a flame.
When fuels burn, the type of flame produced depends on the proportion of oxygen available. When the oxygen supply is insufficient, then the fuels burn incompletely and produce mainly a yellow flame and when the oxygen supply is sufficient, then the fuels burn completely and produce mainly a blue flame.
- Structure of a Flame:
There are three zones or parts of a flame – innermost, middle and outer zone.
- Innermost zone: The innermost zone of a flame is dark or black. It consists of hot, unburnt vapours of the combustible material (candle). It is the least hot part of the flame.
- Middle zone: The middle zone of a flame is yellow. It is bright and luminous. In it the fuel vapours burn partially because there is not enough air so it produces carbon particles which become white hot and emit light. This zone is the major part of a candle flame.
- Outer zone: It is non-luminous zone. It is the outer zone of a flame where complete combustion of the fuel takes place because there is plenty of air around it. It has the highest temperature in the flame.
