What action increases enthalpy in the air molecules of the earths atmosphere?
the air being heated by the sun
What is relation between hydration energy lattice energy and enthalpy of solution?
enthalpy change of solution=enthalpy change of hydration - enthalpy change of lattice
What is one reason to use Hess's law?

Electron gain enthalpy values of hydrogen and phosphorous?
gain enthalpy of phosphorus
How do you calculate the heat of compression for an air compressor?
enthalpy of air leaving the compressor minus enthalpy of air entering the compressor
Define enthalpy and how it is measured?
Enthalpy is a particular amount of heat that is produced or released at a given pressure. There are specific equations that must be used to calculate enthalpy.
How bond formation and bond breaking related to enthalpy?
Enthalpy is the measurement of total energy change of a reaction. The energy of bond formation and bond breaking can be used to calculate the bond enthalpy of the reaction. Bond enthalpy is the enthalphy change when 1 mol of bond is broken. Therefore the general equation to calculate the enthalpy change is energy of bond broken subtract by energy of bond formation.
What is the enthalpy of air at 700 kPa and 450 K?
The enthalpy of dry air at 700 kPa is ~1016 J/kg(degreeC) so at 450K the temperature is 177 C this would make the Enthalpy of dry air ~ 179.832 kJ/kg at 177 C
