Why does increasing the temperature make solutes dissolve in water quicker?

a. it decreases the surface area of the solute
b. it raises the pressure of the water molecules
c. it prevents the solute from crystallizing
d. it makes the water molecules move faster

Calculate the number of molecules present in 0.750 mol of mgo.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
