What is the partial pressure of water vapor in an air sample when the total pressure is 1.00 atm, the partial pressure of nitrog
1 answer:
Answer:
0.0156 atm
Explanation:
Let the partial pressure of water vapor be .
Given:
Total pressure of air sample is,
Partial pressure of nitrogen is,
Partial pressure of oxygen is,
Partial pressure of all other gases is,
From Dalton's law of partial pressure, we know that, the total pressure of a mixture of gases is equal to sum of partial pressure of each individual gas.
So, total pressure of air sample is equal to the sum of partial pressure of nitrogen, oxygen, other gases and water vapor.
Therefore, framing in equation form, we have:
Plug in the given values and solve for . This gives,
Therefore, the partial pressure of water vapor in an air sample is 0.0156 atm.

Explanation:
Kepler's laws have three principal points:
1. planets orbit the sun in elliptical paths
2. the orbial period is related to the orbital distance by
where T is the orbital period and d is the orbital distance, T is in years and d is measured in units of the earth sun distance.
3. planets closer to the sun move faster than planets far away from it.
Newton:
Newton discovered that there is a consequence to the gravity exerted by objects: mass, the heavier the planet, the more gravitational force it posseses ( thats why we orbit the sun)
with the gravitational force newton discovered the inverse-quadratic relationship between the distance of the planets and the acceleration exerted by the force one could exert on another.
Kepler's laws were mostly based on observed evidence with quantitative relationships between the mentioned variables. Newton's laws are based on calculus and symbolic equations. While Kepler's mode is basic, Newton took another step in and build a more general model for gravity (which was improved by general relativity later). In a nutshell Newton proved the scientific causes for Kepler's laws...
