Answer:
Unlike solid and liquid state, molecules in gaseous state show random motion. That is the reason, gases take the shape of container and spread quickly in space. The random motion of molecules in the gaseous state is due to high kinetic energy in molecules. They have weak intermolecular interactions between them. The intermolecular space between gaseous molecules is very large. They can show all the three types of molecular motion, vibrational, rotational and translational motion. In vibrational motion, molecules move back and forth whereas in rotational motion the molecule rotates in space. In translational motion molecules move in certain directions. Molecules of solid-state are capable of vibrational motion due to strong intermolecular forces. Therefore, they show least random molecular motions. Like solids, liquids are capable of vibrational motion but at the same time they can also show rotational and translational motions due to weak intermolecular forces between molecules. Hence, liquids can show random molecular motions but less random compared to gas molecules. So we can say that random motion is related to temperatures, intermolecular forces of attractions, the kinetic energy of molecules and heat transfer.
Answer:
City B will have the highest annual range of temperature
Explanation:
City B will have a higher annual temperature than city A. <u>It is because the northern hemisphere is mainly covered with landmasses but the southern hemisphere is mostly covered by the water body</u>. So there is <u>more absorption of heat on the ground surface and the landmass area</u>. The oceans when heated it reflects some heat energy back into the atmosphere, and some of it is transferred to the land area by the sea breeze.
These events ultimately lead to an increase in the heat amount in the northern hemisphere.
