Tong Research Paper

Why is it written in different fonts? I hope someone did not plagiarize.

I bet you that Tong plagarized...the fool. But we are allowed to "quote"

Lev give me an example of a thesis...and tell em what Joule proved...mailman confused me O_O

post what u wrote man

Sorry I didn't see your post man

James Joules believed that energy does not disappear. Rather it is conserved and it goes to surrounding objects in the form of heat. The independent variable in Joule’s experiment was the stirring of the water with energy. The dependent variable was the water’s temperature. James Joules, along with assistants, built an apparatus to test his hypothesis. He built the apparatus out of four revolving blades that was surrounded by stationary vanes that are connected to a stick that is connected to the bottom of a spinning drum. The revolving blades and stationary vanes are inside a container of metal framework, which is covered by a copper jacket. A rope is tied around the spinning drum. The other end of the rope goes though a pulley and is tied to a weight. There is also a slit to put a thermometer though so the water’s temperature can be measured. Finally a ruler is used to measure how low the weight dropped when it was lowered.

Joules believed that energy is always conserved. To prove this theory, he lowered the weight down by a measured amount. Then he multiplied the acceleration due to gravity with the height that the weight that got dropped is from the ground with the mass of the weight. This gave him the amount of potential energy that got converted to kinetic energy after the weight was lowered. Joules first measured the temperature of the water using a very precise thermometer. Joules lowered the weight, which caused the rope to be pulled on and therefore the spinning drum was spun. This caused the system of paddles to spin the water. Joules then measured the temperature of the water after the paddles stopped turning. The amount of temperature degrees that the water was raised by was approximately the same as the amount of kinetic energy that the lowered weight used on the water. This confirmed Joule’s hypothesis about energy being conserved. This allowed Joule to come up with the equation: CΔT=mgh. Henceforth, Joule was able to determine the specific heat (C) of water too. He was to estimate a mechanical equivalent of 4.41 J/cal. In 1845, Joule read his paper that contained the paddle-wheel experiment, On the mechanical equivalent of heat to the British Association meeting in Cambridge. In 1850, Joule published a refined measurement of 4.159 J/cal. Today the accepted specific heat of water is 4.186 J/cal.

She killed it by all her edits though...

*yawnz* nice

I bet you didn't even read it

i read the first paragraph and almost fell asleep

I will tell you tomorrow. Great mind need rest

Well at least it did something useful ...sleeping is healthy

@Lev: Stop kidding yourself Lev "Great Mind"

i'm smarter than both of u

That's why you lost our competition right?

no i let u win

You betta take those words and get back on the banana boat man

don't call ma house no mo

Don't ca ma banana boat no mo!

ur banana boat is cheap and doesn't have a phone.. noob!

Do you know who you talkin to boi?

i'm talkin to da banana boat girl... girl

Im going to teach you how to not call my banana boat again tomorrow on Banana Boat day

is "Tony" the smartest out of u guyz?

Im smarter than Tony...his actually name is Tong BTW lol

0_0 why the hell are u so dumb, and lev. (ur mom plagiarized !! zzz)

This is Tong's genius:

Tong you noob, just post what you wrote...

James Prescott Joule was an English physicist and brewer. James Prescott Joule's main contributions to the Chemistry field were his study of the nature of heat, and discovery of its relationship to mechanical work. He was also famous for his accuracy in experiments. James Prescott Joule was born into a brewer's family at Salford, England on Christmas Eve of the year 1818. Joule's work experience at brewing and his access practical technology explains why his experiment results were extremely accurate. Although a delicate child, James Prescott Joule did not go to regular schools, but received education from his mother's half sister. Joule's interest in Science emerged after his father sent him to John Dalton, who was one of the most renown chemist, meterologist and physicist of all time. Joule received knowledges on algebra, arithmetic, geometry, and finally, chemistry from Dalton's own master piece "New System of Chemical Philosophy." Dalton's teaching on the constitution of mixed gases, and on the behavior of vapors and gases under heat had greatly influenced Joule, who then studied the conversion of energy and eventually came up with joules law.

and i found some detail about how he came up with that 4.1 something joules
