1. Homework Statement
A student decomposes KCLO3 and collects 35.2 cm^3 of O2 over water at 23.0°C. The laboratory barometer reads 751 Torr. The vapor pressure of water at 23.0°C is 21.1 Torr. Find the volume the oxygen would occupy at 0.0*C and 1.2atm (= 912 Torr).

I'm just curious, when light enters a black hole, does the black hole gain a little bit of mass? We think of photons as massless particles, but they do have energy, and energy has a mass equivalent, e=mc2 Would the mass gained perhaps be, = hν / c2 ?
Hello all,
This is a question on a problem set for my Calculus 1 class. Please help if you can.

A function, f defined on the set of real numbers is said to have even symmetry if f(-x) = f(x) for all x, and is said to have odd symmetry if f(-x) = -f(x) for all x. Use...
Who are the authors of relativity theory? From Wikipedia:
"[Nikola] Tesla also believed that much of Albert Einstein's relativity theory had already been proposed by Ruđer Bošković, stating in an unpublished interview:
...the relativity theory, by the way, is much older than its...
Ok but Lawrence Krauss told me that because of Dark Energy, all the galaxies will eventually be traveling at > c with relation to each other and will disappear from each others' view. He also said that this doesn't violation SR. Explain that!
Hello All,
I'm trying to wrap my head around SR and I have a couple questions: If two space travelers (A) and (C) take off from a Planet (B) in opposite directions and each travels just over 1/2c, do they vanish from each others' view? I don't see why they wouldn't but
If yes, doesn't...
Hello All,
I'm an undergraduate student writing a research paper. The Research question: In scientific principal, is eternal life possible? I'm having trouble finding any relevant sources. I've been e-mailing expert physicists and cosmologists suggesting that dark energy coupled with the...
