Heat Transfer Lab
The following represents a lab set up for heat transfer. The cup on the left started with boiling water at 100 degrees C and the cup on the right has water at 20 degrees C. There is an aluminum bar between the two cups allowing heat to transfer from one cup into the other. The set up will be left alone for 20 minutes and temperatures of each cup of water will be recorded every minute for 20 minutes.

Explanation:
It is known that relation between wavelength and frequency is as follows.
where, = wavelength
c = speed of light =
[/tex]\nu[/tex] = frequency
It is given that frequency is . Hence, putting this value into the above formula and calculate the wavelength as follows.
=
or, =
Thus, we can conclude that wavelength of given radiation is .
Answer:
The total energy of the system is maintained as energy is transformed.
Explanation:
The total energy of the system is conserved.
An ionic compound is arranged in a organised lattice structre that allows for the greatest electrostatic attraction between the opposite charged atoms and the lesser electrostatic repulsion between the same atoms, where the atoms are as closely packed as possible. So the amount of energy (in form of heat) needed to break the electrostatic attraction between the atoms, so this means that ionic compounds have very high melting points.
