Nopes. It is one of my favoutie subjects. Its really easy tooo. All the best!

Difficult, but you would have to change your study habits.\n\nI would recommend getting a spiral notebook for each class, and take notes on the right side only.  Then when you get home, re-write your notes on the left.  It helped me learn more.  \nAlso let your teachers know you are really trying to get your grades up, and see if they can offer any help.  \nTurn in all your home work.\nWhen you take tests, go over your answers to see if they make sense to you.

wow u must b smart to take that class! i dont think so i googled it but i might hav dun it wrong why dont u try googling it!

I was a biology major (unofficially) my freshman year, and I got a GOOD taste of what it is like. I can tell you right now the hardest class for most people is organic chemistry. It was hard for me, and I had no trouble in calculus, 300 level (for juniors) biology classes, and I absolutely aced the general chem classes. You have to memorize a ton of material, AND understand the concepts inside out. Actually, organic wasn't that bad, but I dropped it mid-semester because after reading 300 pages of chemical structures and reactions, I was bored to the point of insanity, and we all know it is hard to do well in something if you're bored. I did have a bad teacher too though.The biology classes seem like more memorization than anything else, so if you have a good memory like me, you should do well in them, but of course you need a basic understanding of chemistry to do well in biology. As always though, if you are truly interested in the subject (I don't think I was), you can succeed.

no, reaction times are too slow at that temperature.  (I'm just guessing, but I'm a chemist.  You should be able to look up reaction energies, try Beilstein.)

Well, this was one aspect of my research thesis in Physics of about 10 years ago. The big picture is quite wide, so let's focus on a particular property of classical thermodynamics that is challenged by the chaotic behavior of certain systems: the equipartition of energy.\nClassical thermodynamics tells us that, providing enough time, a system goes to equipartition, i.e. its energy is apportioned in equal parts along all the degrees of freedom. It is well known that the equipartition law has been disproved by quantum mechanics, but until some years ago it was believed a necessary consequence of classical mechanics.\nThe news is that the recent studies (including my little contribution) have shown that there are certain systems for which, under given conditions, neither classical mechanics prescribe the equipartition of energy.\nA class of such systems is constituted by the nonlinear Hamiltonian lattices, that is, N-dimensional spring/mass chains with nonlinear springs. To make it simple, consider that some solid gasses have their atoms stuffed in crystals that can be modeled as such lattices.\nThese systems are classified as chaotic (or also stochastic) for mathematical reasons too complex to be explained here.\nSuppose you freeze Helium at the point that it solidifies. Then you have such a crystal. Its degrees of freedom are the harmonic modes of oscillation of the crystal (just like the harmonic sounds in a guitar string). From the equipartition law one should expect that, after waiting some time, all harmonics go to the same energy. But this is not the case: most energy remains instead concentrated in the lower harmonics. The effect is stronger as the temperature decreases.\nObviously these results are mainly obtained thanks to computer simulations, because the involved equations have no analytic solution.\nSurprisingly, some of these results match with the prediction of quantum mechanics. This is clearly a debated issue but it suggests anyway that the "old-fashioned" classical mechanics has still something to say in modern physics!\n\nLater addition (in relation to the "Additional Details" above): yes, of course I'm speaking of deterministic chaos here, in the mathematical sense (thought it was obvious).

I have a really good, comprehensive table of the Enthalpies, Entropies and Gibb's free energy that I use, I wish I could give it to you, but I forgot where I got it, I only have a hard copy.\n\nYou may be able to search around the internet and find some good tables, but they wont likely be very comprehensive.\n\nOne good source would be the back appendix of a college level chemistry books.  These books usually have a pretty good table of enthalpy/entropy in the back, plus lots more info.  You can pick one up cheap at a used book store I am sure since it doesnt really matter how old the book is.

Most difficult are supposed to be Chemistry, Biology, Physics, Spanish, German, French, History, Double-Award Science, Geography.\n\nEasiest are supposed to be English, PE, Media Studies and Drama.\n\nI can't find the full table, but there is a report from The Times at: http://www.timesonline.co.uk/article/0,,2-2113241,00.html

i dont think it is very hard

What kind of classes? Different ages and/or grades? A combination of different subjects?

A thermal power plant uses heat.  I don't know what a 'themal" power plant is.  If you can't operate a spell-checker, I doubt you have the gray matter to expend on thermo-dynamics.

I don't think either one is easier.  It depends on your interest and/or aptitude.  My degree is in chemistry and I think it is easier than physics.  I'm sure physicists think physics is easier than chemistry.

i doubt your teacher couldnt answer these unless (s)he is not actually a physics teacher\n\nc and a\n\nthe initial momentum is 4kgm/s\nthe final momentum is conserved so it is still 4 kgm/s\nmomentum is mass*velocity\nmass is 1+3= 4kg\nv = p/m = 4kgm/s / 4kg = 1 m/s\n\nentropy is randomness or disorder, when the rooms are different temps, its like the temps are "sorted". there is order to the temperature. when they combine, there is no more order, the temperatures are more random instead of being focused around 2 different temps so disorder, or entropy increases

Lisa S. Said:\n\n"Amazon lists this one as being highly rated (five stars) --Chemical Engineering Design and Analysis : An Introduction (Cambridge Series in Chemical Engineering) (Paperback)-- around $25 used."\n\nHey!  My first Chem E professor wrote that book!\n\nI'd agree it's a very good book for a first course in ChemE, and it is the only text book I bought that I actually read cover-to-cover.  At Berkeley, that book was used for the introductory course on "Material and energy balances applied to chemical process systems. Determination of thermodynamic properties needed for such calculations. Sources of data. Calculation procedures."\n\nI would definitely second that book as a recommendation.  It does a great job of preparing you for everything else to come, and the line of reasoning is very coherent.  Rather than just throwing some mathematical tools at you, it gives you the sort of comprehension necessary for performing intelligent analysis.

Look into physical chemistry - very math oriented.  PChem I is usually a quantum chemistry course which deals with lots of calculus and physics material.  PChem II usually focuses more on thermodynamics laws and is also very math and physics intensive.  Some physical chemists become theorists (they often work with computer programs and do 'computational chemistry') while experimental physical chemists work on a broad range of research interests.  You may also want to look into analytical chemistry and chemical engineering.  You should talk to some professors or academic advisors at your school for some more advice on which courses to take and help in making your decisions.  Good luck.

It really depends on your skills and interests. I had two roommates in college taking chemical engineering. One was able to breeze through all the courses. The other one struggled but he really liked the courses so he stuck with it and did just fine.\n\nDon't worry about what is hard, follow the direction you enjoy. In the long run that is the best.

Yes but is very difficult.
