A 25.0 g piece of aluminum (which has a molar heat capacity of 24.03 J/oC mol) is heated to 93.1 oC and dropped into a coffee cup calorimeter containing water initially at 19.9 oC. The final temperature of the water and aluminum mixture is 23.1 oC. Calculate the mass of water in the calorimeter. The specific heat of water is 4.184 J/g oC.

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.
