The compressibility ratio of a gas is PV/nRT. What happen to the compressibility ratio if the attration force between the gas molecules increase? The answer says it decreases because the more molecules interact with each other, so the pressure they exert on the container decreases, thus...

Help!photoelectric effect Hi guys, for an electron to jump from a lower energy to a higher energy state, it must absorb photons that correspond to the difference of the these 2 enegry states. I am wondering if it is okey for an electron to absorb greater frequency of photons(greater energy) to...

HELP!Capacitors in circuit Hey guys, I have a short question here. If a resistor and a capacitor are connected in a series, it takes 2 seconds for the capacitor to to have a voltage of 2V, what happen to the voltage across the original capacitor if another same resistor is added in series? The...

I totally understand now..thanks a lot

Urgent!Isothermal process Hi guys. i have a very short question. In an isothermal process, change is temperature is zero, so change in internal energy is zero, thus Q=W. The part that i am confused is that if Q=mc(deltaT) then should be a change in temperature in the isothermal process? Thanks...

Hi, guys, i tried to read the definitions of laminar and turbulent flowon some of the website, but had difficult time understanding them. I am wondering if you guys can explain the above terms in more plain words?

Thanks a lot for the response. Blue has a greater index refraction than red, so should red bend more the second time than blue if snell's law holds true?

Hi guys, I just have a short question. A prism splits white light into it component color depending on the wavelength of the color. As the wavelength decreases, the index of refraction increases, so the wave bends more. However according to Snell's law, a greater index of refraction results in...
