The town of Grindelwald, Switzerland sits at an elevation where the atmospheric pressure is 0.88 atmospheres, and the pressure at the summit of The Eiger, a nearby mountain, is 0.72 atmospheres. What is the pressure difference between these two elevations in kilopascals?

The difference between the atmospheric pressure of the two elevation is 16.212 kPa

Explanation:

To convert the pressure from atmospheres to kilo Pascals, we use the conversion factor:

1 atm = 101.325 kPa

We are given:

Atmospheric pressure of Grindelward, = 0.88 atm

Converting the atmospheric pressure of Grindelward:

Atmospheric pressure of the Eiger, = 0.72 atm

Converting the atmospheric pressure of the Eiger:

Difference between the atmospheric pressures of the two elevation,

Hence, the difference between the atmospheric pressure of the two elevation is 16.212 kPa

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
