Bragg's law (Sir W.L. Bragg; 1912)
While a beam of x-rays strikes at crystal surface wherein the layers of atoms or ions are separated regularly, the maximum intensity of the reflected ray takes place while the complement of the angle of incidence, theta, the wavelength of x-rays, lambda, and the distance among layers of atoms or ions, d, are associated by the equation
2 d sin theta = n lambda,
Where n is an integer.
When water is boiled under a pressure of 2.00 atm, the heat of vaporization is 2.20 x 10^6 J/kg and the boling point is 120Degrees C. At this pressure, 1.00 kg of water has a volum
