The specific heat of water and steam (water vapor) are 4.18 J/g C and 2.10 J/g C respectively. Heating a 74.0 g sample of water from 88.3 C to water vapor at 112.5 C requires 172.58 kJ of heat. Calculate the heat of vaporization of water in kJ/g. Assume the boiling point of water is 100 C

What is the mass of 4 molecules of co2

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.
