Solution Preview

a) X-ray technologists are very familiar with how x-rays are formed. X-ray machines build up an electric potential, or potential difference between two pieces of the machine. One end of this machine is a wire which when heated, releases electrons. The other end, a receiving end, attracts these electrons via the potential difference. When the button is pressed on the x-ray machine, these electrons fly towards the highly ...

  • Solar Power: Photovoltaics

    Solar power is used synonymously with solar energy or more specifically to refer to the conversion of sunlight into electricity.

  • Number of Photons Produced in an X-Ray

    This solution shows how to calculate the number of photons produced for each incident X-ray, given the X-ray's energy, wavelength, and energy conversion coefficient.

  • the Sun in equilibrium

    As the radiant photons gradually bounce their way from the fusing core of the sun and out thru the radiative layer above, they create even more heat by knocking their way up thru the layers of dense gas (kinetic energy = heat).

  • How do lasers work?

    If you have many atoms in some excited state then the photons from one decaying atom can make other atoms decay much faster leading to more photons and more decaying atoms etc.

  • Inelastic collision causes loss of momentum

    Hence the causes of energy loss in collisions are conversion of energy into the heat energy, because both objects absorb the K.E. and their temperature is increased. And also when two objects collide, sound is produced.

  • knowledge of the atom

    If we shine a source of continuous spectra EM radiation on a material, some of the photons will be absorbed (converted to heat) or be deflected from their path to the detector.

  • Latent heat and energy during a phase transition

    Change in energy or energy absorbed when iceat 273 is converted to water at 273 K The heat absorbed when unit mass of ice is melt into water is called latent heat l1.(More clearly it is the specific latent heat of fusion of ice).

  • Calculating heat of the reaction from activation energy

    (ANS)

    Reactions which have a negative value of DH , i.e., DH < 0, are said to be EXOTHERMIC, and energy is released (usually as heat) during the conversion of the reactants into products.

  • Law of Thermodynamics and Life on Earth

    The organic matter is oxidized within the bodies of these animals turning it again into water and carbon dioxide (and since the conversion is not 100% efficient also into various amounts of waste products of organic matter).
