The kinetic molecular theory of matter offers a description of the microscopic properties of atoms (or molecules) and their interactions, leading to observable macroscopic properties (such as pressure, volume, temperature). An application of the theory is that it helps to explain why matter exists in different phases (solid, liquid, and gas) and how matter can change from one phase to the next.
Answer:
he difference between X-rays and visible radiation is in the energy of each foton.
Explanation:
Visible light and X-rays are electromagnetism waves with the same origin betray the atomic, but the energy of transioin wings is different,
E = h (v_f - v₀)
With this equation we see that the energy is proportional to the difference between the atomic levels where the ranscion occurs, the X-rays the transition involves deep levels n = 1 or 2 for which the energy of the emitted photon is very high.
The visible radiation the transition is between levels closer so that the emitted light has a lower frequency and is in the range of the visibly
Consequently, the difference between X-rays and visible radiation is in the energy of each foton.
Answer:
It cannot reach us by conduction or convection as there is no medium such as air in most part of the space between the earth and the sun. From the sun the heat comes to us by another process known as radiation. The transfer of heat by radiation does not require any medium.
