Answer:
The molecules inside the ice pack are frozen therefore they are stuck in place. The molecules inside an insulated cup aren't frozen but still stuck inside of their container so that they can not fly out.

Answer / explanation:
How does concentration affect boiling point of a solvent?
The amount by which the boiling point is raised is directly dependent on the concentration of the solute.
The higher the concentration of a solute, the more it is said to be difficult for the solvent molecules to escape into the gas phase.
However, when a non volatile amount of substance is dissolved in a given solvent, the boiling point of the given solvent increases.
The higher the concentration, the more higher the boiling point of a solvent.
It requires a higher temperature for enough solvent molecules to escape , this the boiling point is raised elevatedly
Answer:
Explanation:
Sn(WC)2
if it is tungsten carbide this should be correct but there are many versions of carbide
Sn(MC2)2
could also be possible
the 2 next to MC should be a subscript
Answer: Gunpowder
Explanation:
Gunpowder is made by mixing potassium nitrate with two fuels (atoms that can combine with oxygen atoms and release energy), carbon (charcoal) and sulfur. The oxygen atoms leave the nitrates and move onto the carbon and sulfur atoms, releasing a buttload of energy.
Answer:
76.9L
Explanation:
Based on the graph, whenever the temperature increases by 100K, the volume increases by 10L, so do 769/10
