By: TripTraverser. on 01 Dec 11, 01:58:45
There is no temperature change when the molecules are changing phases because the energy is being used to change states of matter instead of change temperature. Ice expands when cooled because of the optimization of the hydrogen? bonds. (that's why ice floats, it moves farther apart and becomes less dense than water.)

By: fanchemii. on 26 Jul 11, 09:41:53
I don't get how you got grams out of Joules when you divided 125,340 over 354.95. Could you please explain. Also, it actually matters whether you have Kelvins or Celsius degrees. 60 Celsius degrees is 333.15 K, which makes a difference. If you don't convert Celsius degrees into Kelvins the units will not cancel out. Therefore, your calculations are wrong. And if you do have something at 60 Kelvin then? it's pretty cold anyway (-213 Celsius degrees).

By: vininnz. on 02 Jan 11, 03:32:15
You are referring to Kinetics, which refers to the RATE at which a particular transformation or reaction occurs. All questions related to thermochemistry, like the one addressed in the video, deal? with thermodynamics. Thermodynamics only concerns the initial and final (equilibrium) states and does not concern the rate at which a particular transformation or reaction occurs.

By: MsChaChingChaChing. on 10 Jun 10, 18:18:13
wait but shouldn't time play a factor? the problem never states how fast you want the water to go down to 0degrees C. you only say it needs to cool down. cna't i just place a big chunk of ice, so that it goes down to 0 degrees C but maybe even go past it? the problem never specified it had? to stay at 0degrees C, so i can cool it down past 0 degrees C.

public Listrnode (int item, Listnode next) { this.int = item; this.next-next; } The key to understanding the syntax is that objects and methods pass objects by reference so that the parameter "Listnode next" is not the object next of type Listnode but only a reference i.e. a pointer) to the object? next of type Listnode, where the reference contains the address in live memrory where the first byte of the object can be found. Whether the object "next" has already been created is a separate issue.

By: SuperSplat7. on 29 Feb 12, 21:10:12
What you do is amazing! I have found some of these relevant chemistry videos very very helpful. I learn more in 15minutes than i do in a class where we cover the same thing in 50 and i still dont understand it. Anyways what would be GREAT is if you could have a team that agrees with doing things for? free so there could be a much wider useful youtube channel/s of knollege. What you do is brilliant BUT you need a TEAM! Teams get more done! Keep up all the good work

By: effortless35. on 06 Mar 11, 23:17:20
It doesn't. Fixing C3 doesn't restrict your possible choices for C4. Take any pair of C3,C4 and you'll get a particular solution of the differential equation. To? state it differently, for any complex numbers C3, C4 you can find complex number C1, C2 such that C3=C1+C2 and C4=i(C1-C2)

Quick question ...
By: bob9630. on 20 Feb 11, 22:27:40
Quick question about the relationship between C3 and C4. Since C3=C1+C2 and? C4=i(C1-C2), are the choices for C3 and C4 truly arbitrary, or does choosing one, affect the choice for the other?
