Explanation:
The given data is as follows.
Heat transfer coefficient (h) = 12
Plate temperature (
) = 
= 303 K
Steady state temperature (
) = ?
Hence, formula applied for steady state is as follows.
= 
Putting the given values into the above formula as follows.
=
= ![5.67 \times 10^{-8} \times [(30 + 273)^{4} - T^{4}_{2}]](https://tex.z-dn.net/?f=5.67%20%5Ctimes%2010%5E%7B-8%7D%20%5Ctimes%20%5B%2830%20%2B%20273%29%5E%7B4%7D%20-%20T%5E%7B4%7D_%7B2%7D%5D)
= 282.66 K
= (282.66 -273)
= 9.66
Thus, we can conclude that the steady state temperature will be 9.66 .
The dissolution of a solute in a solvent to form a solution usually occur in three steps, which are delta H1, delta H2 and delta H3.
For dissolving an ionic solid, the lattice energy, which is the energy that is holding the ionic particles in place correspond to DELTA H2 and it is the energy that must be conquered. The higher the charge in the ionic solid, the higher the lattice energy. The lattice energy must be overcome in order for the solid to dissolve.
Answer:
The electrons where in motion
Pure substance element I think
Answer:
A well tested explanation of a natural phenomenon
Explanation:
A scientific theory is an explanation of a natural phenomenon which has been drawn from a well tested observation.
Theories are products of repeated scientific experiments. When a hypothesis otherwise known as a "scientific guess" survives a lot of scrutiny, we can elevate it to the status of a theory. Most theories starts off from simple observations. These observations can further spark series of experiments in such a field and a scientific guess proposed. Further testing and experimenting would now lead to a theory.
