Answer:
The particles of the liquid slide around faster as the kinetic energy of the particles increases.
Explanation:
After all the bonds in the solid state are broken in part CD, the more free particles in the liquid state gain more kinetic energy with increase in energy supplied.
The increase in kinetic energy is indicated by the temperature increase thus the positive gradient of the part CD.
Kinetic energy means more vibrations thus the particles slide more and more against each other.
1 liter of O and 1 liter of NE have the same number of molecules.
1.For the first one, I'd say B, because the distance between each continent is greater than it was back then, allow for the mesosaurus to travel that distance.
