Two gas jars are connected to each other, but they are separated by a closed valve. one gas jar contains oxygen, and the other contains hydrogen. what will happen when the valve is opened?

oxygen and hydrogen molecules will mix because of random movement of their molecules.

oxygen and hydrogen molecules will remain in separate jars because of different partial pressures.

oxygen and hydrogen molecules will remain in separate jars because of different rates of expansion.

oxygen and hydrogen molecules will mix because the molecules have a much lower volume than the volume of the jars.

i think its a or d

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.
