Thermodynamics

Topic

My topic in this assignment is the physics of thermodynamics and how thimagesermodynamics works. Also talking about what is thermodynamics and how it can improve the way we travel and make us move faster. Do not think that thermodynamics Is only about steam engines it is almost about everything in this world.

 

 

 

Issues

Thermodynamics is a wide types of topics in science and engineering. In the past thermodynamics  was developed to make and achieve better power for steam engins. This began in the nineteenth century when steam was a big topic. Then various other range of machinery were invented as well as heating and pumps.Obviously as time Picture5went by many mistakes and accidents happened, but they learnt and adjusted their mistakes accordingly. Although science has made a big leap forward since then. But now they face big challenges from the very technology they invented on  they cause on the environment.

 

Solutions

From steam to combustion to fossil fuel and electricity, scientists have strived to develop new technologies for us humans to travel faster, and lead a better and comfortable life, but environmently a big problem has rang alarm bells with regard to pollution. So now, solarUnknown energy, wind power technology are the focus, to cut down at least on these emissions and harmful substances and their effect on the environment. Consumer demand nowadays outstrips supply, scientists and media alike are trying to inform and create awareness amongst consumers and educate them as to how to use energy effectively and reduce unnecessary waste.

Technical science behind why the solution works

Innovation and clean science and technology is the answer to the problems and challenges we now face to save our planet. From classical thermodynamics to advanced science and technology. This century ( scientists believe) we will harness solar, hydrogen,hornet01b-300x249 wind power (to replace fossil fuel), especially solar energy could one day be exported to earth from one of nearest planet, this of course will put a stop on pollutants and give the future generations a better cleaner energy. The other thing is magnetism to be able to travel faster than ever before, magnetic trains are already in use in China, so magnetic car are also possible, hovering and floating above ground.

Success of solution

Understanding the role of thermodynamics in development of technology, was a starting point, now we need clean energy to be used. The problem is how do we harness that energy. Science and technology innovation is moving at ever greater pace much faster imgresthen ever before and I am sure a solution will be found in not to distant future. The maglev train that floats above ground has been carrying humans at great speed and it is only a matter of time before we see similar things like it invented.

Parts of the issue still exist or are not completely fixed by the solution

Scientists are I am sure too busy actually creating new innovative things in their labsspaceshuttleclimbout3.jpg.w560h420, looking for lasting solutions and breakthroughs , there are still a lot or parts of things that need to be completed, be it solar power for electricity, generating magnetism for solving transport pollution problems to achieve their goals of energy free pollutant technology, after all, lots of fictional things are becoming reality.

Major positive consequence

We all believe in science and technology to save us from the hidden dangers. Science andimages-1 technology has come a long way, in innovation, improvement from clean fuel to low emmission boilers, electric cars and lots of other low energy consumption machinery and other gadgets. Awareness and educating humans is the key about the care of our environment to achieve the aim of clean and healthy future.

Major negative consequence

If we look at the nuclear power for example, it has provided energy of electricity for millions but after Chernobyl and the latest Fukushima nuclear disasters many countries are havingfzz3 second thoughts and are looking at other ways, be it gas turbines, even coal as an alternative but they have their downside on the environment. Science and technology might provide better alternative , like solar power, but still a long way in supplying the ever growing demand.

 Overall consequence

Many disasters happens a long way from home, and after a little while, we seem to forget imageif similar disaster comes knocking at ou door. Nowadays science an technology produce both positive and negative results this is a serious challenge for those who believe in science and technology, who focus always on the positive side of technology and ignoring the negative side of things.

Worthwhile for society

From the age of steam engine, combustion engine, cars, planes, and electric trains etc…made society and technology were it is now, without that beginning, we would not be were we are now. As a consequence  we are able to see were science and technology willtrim-technology take us in the coming future. Science is not static it is exploding all around us. Innovations and discoveries are changing the whole economic, political, and social landscape.

Successful of solution in addressing the issue

We are now able to see the direction that science and technology will take in the very near future. Scientists predict wonders in innovations. images-3Things are changing fast in all aspects of science and technology, they will solve all the problems our world faces and solve all other  problems head on.

 

 


Iron ore

What is Iron ore?

Iron ore is a rock from which metallic iron that can be economically extracted. It is used for construction, car production, white goods and etc…, it is a rock which is very reliable. Around 98% of the world’s ironmagnetite_rock-mineral ore production is used to make iron into a form of steel.

 

The issue of iron ore

To find iron ore is a really challenging process,  when each massive truck collect the Earth from the site, usually containing 60% iron ore the rest is just earth. The companies do surveys IMG_1811before hand to make sure that the said percentage is obtained because there are risks the investment can go wrong, and lose lots of money.

Solution

Before it wasn’t easy to find iron ore. The companies before we’re guessing where iron ore was, now they have super advanced technology, first they start with geologists that  have access to labs, they do a survey for the areairon_ore_mines_050115.Then they find out the consistency of rocks in the area. After, they confirm the area, the work begins,the engineers play their role of planning how to excavate the earth and give the go ahead.

The process of Iron ore

Finding iron ore is not easy, it is a rather challenging process. Iron ore is naturally found in the earth. It is collected from the earth with huge big trucks then taken to the factory. The big trucks dump the load to a dumping area.Then special earth 97f5059cedbee0555afa9626760eee27938c3e5clifters take the earth to a conveyor belt that leads to the furnace.  Iron is extracted from iron ore in a huge container called a blast furnace. Iron ore such as having hematite contains iron oxide, The oxygen must be removed from the iron oxide to leave it behind by it self.  Carbon is more reactive than iron so it  can push out or displace the iron from iron oxide. So what happens is iron oxide plus carbon makes hard iron plus carbon dioxide. The blast furnace should be at 1200 degrees celsius and separates iron ore from the earth. At the end as a finished product iron ore comes out as linear billets.

Social, economic, cultural

The social, economic, cultural and in most cases political. positives are: so long as iron ore is in demand and prices are stable countries we’ll see a major development, but on the negative side if demand is sustained, environmentally disastrous, meaning  burning more fuel which is not a good thing. Consequently the solution has lots of advantages for human development. Overall I think the positive consequences is stronger then the negative consequence because development is necessary for the human kind.
