1.
Absolute zero temperature (0 Kelvin or -273.15 °C) is defined physically as the theoretical temperature at which:
The volume and pressure of an ideal gas theoretically extrapolate to zero and translational molecular motion reaches its quantum minimum
Water reaches its maximum density
All liquids solidify into glass
Atmospheric air completely combusts
2.
The Ideal Gas Law combining all empirical gas relationships is mathematically formulated as:
P / V = n * R * T
P * T = n * R * V
P * V = n * R * T
P * V = m * g * h
3.
A 3D holographic plate differs fundamentally from an ordinary 2D photograph because it records:
C) Only the shadow of the object
B) Both the amplitude and phase difference of light waves via interference
A) Only light intensity and color
D) Thermal infrared radiation alone
4.
According to the Egyptian Physics syllabus, what is the valid physical deduction for: Einstein's Photoelectric Equation and Work Function?
Increasing light intensity increases the maximum kinetic energy of emitted electrons
Work function E_w is universal and identical for all metals
Photoelectrons are emitted only if the incident photon frequency exceeds the threshold frequency (ν ≥ ν_c), and maximum kinetic energy is KE_max = hν - E_w, independent of light intensity
Photoelectron emission occurs at any frequency if intensity is high enough
