Answer: The molecules heat up and eventually form water vapor.
Explanation:
As the water moves toward equator, being more warmer zone, the molecules heat up and form water vapor. The water vapors rise up and cool and condense. The condensed water vapors clump together to form clouds and when these clouds become heavy, precipitation occurs and water falls back to oceans and rivers.
A river flows from approximately 45° north latitude toward the equator, as shown in the diagram below. As the water molecules in the river approach the equator the next to be happen is t<span>he molecules heat up and eventually form water vapor. </span>
You need to find moles of the gas, so you would use the ideal gas law: PV=nRT Pressure Volume n=moles R= gas constant Tenperature in Kelvin n= PV/RT (1.00atm)(1.35L)/(.08206)(332K) = 0.050mol Molar mass is grams per mole, so (3.75g/.050mol) = 75g/mol
