  • Equation of state for ideal gas from Helmholtz free-energy
    I would say yes From Maxwell relations we have "S= -∂F ∂T" for V=const Insert in the definition of F, put F under the derivative wrt T and obtain : -U T^2 = ∂ ∂T ( F T) Then simply integrate No other assumption in this derivation
  • How does evaporation affect the temperature of the air?
    The temperature of the air should definitely increase, As the water cools ,its means the air molecules carrying the extra energy transfers it into the atmosphere And this has little to do with surface tension, as surface tension is a result of the top most layer of the liquid which more or less remains the same So its only beacause of the 1# that the air warms
  • Questions about Thouless-Kohmoto-Nightingale-den Nijs (TKNN) paper
    I am reading the famous and concise Thouless-Kohmoto-Nightingale-den Nijs (TKNN) paper Quantized Hall Conductance in a Two-Dimensional Periodic Potential, Phys Rev Lett 49, 405–408 (1982), where I
  • What does a non-perturbative theory mean? - Physics Stack Exchange
    I'm a science writer and I'm having difficulty understanding what a non-perturbative approach means I thought I understood what perturbative meant, but in looking for explanations of non-perturbat
  • electromagnetic radiation - Why does high frequency have high energy . . .
    Planck's constant is a conversion factor which changes the units of energy from a classical basis (as joules, for example) to a quantum basis which has wavelength (and therefore frequency) in it: E = hc (lambda) Note that if we write the laws of physics in natural units then energy has units of 1 (seconds) or "per second", which also gives you the tie-in to frequency i e , "cycles per second*
  • How does water help extinguish fire? - Physics Stack Exchange
    How does water extinguish fire? Heat energy from the fire is transferred to the water, isn't that how it works? How does water deprive oxygen and stop combustion? How is the specific heat of water
  • Why is Iron the most stable element? - Physics Stack Exchange
    The Bethe-Weizsäcker formula offers some explanation for nuclear binding energy However, why the minimum is attained for iron depends on the parameters of the Bethe-Weizsäcker formula, which in turn depend on the specifics of the forces between the nucleons and asking why they are, how they are, is unphysical
  • Can someone please explain magnetic vs electric fields?
    Consider that there are two fields at the point: electric field $\textbf E$, and magnetic field $\textbf B$ Both fields act on charge, but in different manner Electric field is acting on charge as follows: it accelerates the momentum vector of the charged object in the direction of the vector $\textbf E$, and the magnitude of acceleration is proportional to the magnitude of the vector
  • What does the $c$ in $eV c^2$ stand for? - Physics Stack Exchange
    I don't understand the downvotes on this straightforward question with a straightforward but hard-to-search-for answer
