Answer:
C)
the potential energy is increasing through steps A & B, then decreases at C.
Explanation:
Absorbance values greater than or equal to 1.0 are too high. If you are getting absorbance values of 1.0 or above, your solution is too concentrated. Simply dilute your sample and recollect data . Keep in mind that absorbance is the logarithm of the transmission (T) of light through a sample

The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms
Answer:
(1) The sample should not be large, because a large sample would produce a higher and broader mp range.
(2) The rate of heating does not matter.
Explanation:
(1) The sample should not be large, because a large sample would produce a higher and broader mp range, because varying temperature range across the body will lead to inaccurate determination of melting point.
(2) In principle, the melting temperature is INDEPENDENT (not dependent) on the heating rate. so in other words, altering the heating rate does not affect the measure of melting point.
