Thank you. But if it tells me to write v1 in terms of dt and Beta, then doesn't that mean I have to get rid of the V term?
Here's some more equations, I don't know if it will help.
Specific heat is C
Q is heat added or lost to the system
deltaU is the change in internal energy of the...
"Measured heat capacities of solids and liquids are almost always at constant pressure, not constant volume. To see why, estimate the pressure needed to keep V fixed as T increases, as follows.
a)First imagine slightly increasing the temp of a material at constant pressure. Write the change...
Yeah, I thought about that. It was something that I heard and wondered if there was anybody out there that already knew. If I have time, I'll do the experiment one day and see how it goes. Until then, I'll leave it up in the air.
Ok, after reading on this topic a bit, the only reasonable answer I could get was that the aspirin prevents any harmful bacteria from getting in the water. Does anyone know if this is the only reason, or the reason at all?
With all the events happening in Japan right now, I was wondering, what exactly happens during a nuclear meltdown? I have a decent idea of how the plant produces power, but I have no idea what happens during the meltdown to create such a hazardous situation.
Does the Physics Forums edit posts? A couple of comments were deleted from this one, including my own. I don't like negative back-and-forths, but I also respect freedom of speech. Can someone tell me what happened to those posts? I have backups if anybody wants to see what I mean.
Thanks, hypatia. When I first heard that running warm or hot water over your skin to open the pores to let more heat out, I had serious doubts. Hot water might open the pores but it still adds a lot of heat to the system, so any benefits are immediately countered. Most of what I've read and...
I have heard that warm water helps to open the pores of your skin, and therefore, can release more heat which will aid in the treatment of a sunburn. I was immediately skeptical, but after a few searches I found answers both for and against it. What are the actual physics behind this, and, if...
