The mineral that's illustrated based on the information given will be magnetite.
<h3>What is a mineral?</h3>
A mineral simply means any pure substance that has a unique composition and structure.
Since the mineral is black and will stick to you when you walk through the sand at the beach, it's magnetite.

Intermolecular forces are forces of interaction that are operative between two different molecules. They are of follow types
1) Dipole- dipole interaction
2) Hydrogen bonds
3) vander Waal's forces
Depending upon the polarity and constitution molecule above forces are operable.
for instance, in case of ammonia, Hydrogen bonds exist because hydrogen atom is attached to electronegative element i.e. N
HCl and CO are polar molecules, so dipole-dipole interaction is operative in these molecules.
Finally in case of CO2, vander Waal's forces of interaction is operable because it is a non-polar molecule.
In the combined gas equation, (P1V1)/T1=(P2V2)T2, where P1 is the initial pressure, V1 the initial volume, T1 the initial temperature,P2 is the final pressure, V2 the final volume, T2 the final temperature,
substituting for the values: (155kPa× 1.00L)/273K=(500kPA× V2)/408K
V2=(155kPa×1.00L×408K)/(273K×500kPa)
= 0.463L
Sunspots have strong magnetic fields, thus being much cooler than their surroundings. Yet, they are still individually very hot and can reach up to a temp of 3,800 K. But since they are cooler than their surroundings, they appear to be much darker to the visible eye.
