excellent example of this variation. Near the ground‚ where most burning is occurring‚ the fire is white‚ the hottest color possible for organic material in general‚ or yellow. Above the yellow region‚ the color changes to orange‚ which is cooler‚ then red‚ which is cooler still. Above the red region‚ combustion no longer occurs‚ and the uncombusted carbon particles are visible as black smoke. The common distribution of a flame under normal gravity

Energy Energy can neither be created or destroyed‚ only changed into different forms. Energy is only useful when it can be converted into different forms. Energy is often dissipated - spread out and lost. 9 types of energy: Thermal (heat) - flows from hot to cold objects Kinetic (movement) - anything that is moving has this Light - from the sun‚ light bulbs et cetera Elastically potential - when things are stretched Gravitational potential - anything that can fall Electrical - whenever

Global warming You have probably heard about the phrase “global warming” hundreds of times. But what exactly does global warming means? Global warming is not about having a hot day or week or month in one part of the world. It has to do with the average temperature worldwide. Simply put‚ global warming is the unusual rapid increase in earth’s average temperature worldwide. The warming of the earth began in the mid 1800’s. In the beginning it was small and very slow but then in the 1980’s the

a surface. Albedo varies depending on the amount of cloud cover‚ the angle of the sun‚ the particle matter in the air and the surface area (Lutgens‚ Tarbuck‚ Tasa‚ 2011).Thus a higher albedo indicates a surface that absorbs less heat‚ and remains cooler. There are several factors that cause higher temperatures in urban area like dark rooftops‚ dark asphalt surfaces‚ and more buildings with more emitted heat from air conditioners and furnaces and denser traffic which cause elevated emissions of air

Rotary kiln is composed of main drive system and auxiliary drive system‚ and kiln and cooler transmission system are relatively simple. Rotary kiln has two drive systems and their roles are: The main drive system are composed of main motor‚ reducer‚ gear‚ ring gear‚ and cylinder. When sufficient speed ratio and capacity of the reducer are deficient‚ you can add a semi-open gear drive between the reducer and gear ring gear‚ and a small number of kilns can be added a belt drive between the motor and

own land. Now in the era of Youtube‚ young people grow up with easy access to an international culture and so when they go to the cinema‚ they expect to see films that reflect that international culture and for them a Hollywood blockbuster is much “cooler” than a serious film in their own language. A second reason why internationally produced films tend to dominate the domestic market is financial. The two great centres of world cinema‚ Bollywood and Hollywood‚ have studios with budgets of billions

convenient. You aren’t set to pack the kitchen sink in it‚ however you need one that is huge enough to convey the nuts and bolts. A little fishing supply bag makes a great emergency treatment pack‚ or you can utilize something as basic as a resealable cooler sack. Think about the sort of medical aid unit you want to assemble‚ and where you will keep it.

They are vital in maintaining the balance in our atmosphere. The greenhouse effect is mostly a result of the sunlight’s energy and the clouds that absorb and reflect heat. Without the greenhouse effect‚ earth would be less than 33 degrees Celsius cooler. Human activity increased the percentage of gas‚ which increased the temperature. Population growth is one of the major causes. With the increase of population‚ the needs and wants increase. The more demands of the people‚ the more the industry
