What is the partial pressure of water vapor in an air sample when the total pressure is 1.00 atm, the partial pressure of nitrogen is 0.79 atm, the partial pressure of oxygen is 0.20 atm, and the partial pressure of all other gases is 0.0044 atm?

Partial pressure of water vapor = 0.0056 atm

Explanation:

Given that

Total pressure = 1 atm

Partial pressure of nitrogen = 0.79 atm

Partial pressure of oxygen = 0.2 atm

Partial pressure of other gases = 0.0044 atm

We know that

Total pressure = Sum of partial  pressure of all gases.

Total pressure= Partial pressure of nitrogen+ Partial pressure of oxygen+ Partial pressure of other gases +Partial pressure of water vapor

So now by putting the values

1 = 0.79 + 0.2 +0.0044 + Partial pressure of water vapor

Partial pressure of water vapor = 0.0056 atm

a straight line sloped

-first use of geothermal energy occurred more than 10,000 years ago in north america by american paleo-indians

-the first industrial use of geothermal energy began near pisa, italy in late 18th century

-in 1904, italian scientist piero ginori conti invented the first geothermal electric power plant in which steam was used to generate the power

-with the above experiment, the first geothermal plant in usa started in 1922 with a capacity of 250 kilowatts

-however, in 1946 first ground-source geothermal heat pump installed at commonwealth building in portland, oregon

-during the 1960’s, pacific gas and electric began operation of first large scale geothermal power plant in san francisco, producing 11 megawatts

-in 1973, when oil crisis began many countries began looking for renewable energy sources and by 1980’s geothermal heat pumps (ghp) started gaining popularity in order to reduce heating and cooling costs

-as effect of climate change started showing results, governments of various countries joined hands to fight against it, for which kyoto protocol was signed in japan in 1997, laid out emission targets for rich countries and required that they transfer funds and technology to developing countries, 184 countries have ratified it
