Explanation:
First, get both values into the same units
To covert from Kelvin to degrees C, subtract 273.15
1210 - 273.15 =936.85
Melting point of germanium=936.85 degrees C
Melting point of gold= 1064 degrees C
Therefore germanium would melt first because it has the lower melting point.
Paper chromatography can be applied to "ink" to determine if it is a pure substance or a "mixture" of pure substances (in which two or more pure substances are combined). Since, tested with paper chromatography, "ink" separates into its constituent pure substances, Ink is a mixture.
I hope this helps.

Have the same acceleration/reach the ground at the same time.
The two liquids made a new substance.
<h3>What is a physical and chemical change?</h3>
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity.
A chemical change occurs when some substances are transformed into different substances, with different nature and properties. In this case when both liquids are mixed a solid is formed. This is an example of a change of state of the liquids reactants to the solid product, which has properties and characteristics different from that of the initial liquids of the mixture which is called a chemical change.
Hence, option D is correct.
