Define the following terms: A. Humidity
The moisture content of air
B. Absolute humidity
The mass of water vapor contained in a certain volume of air
C. Relative humidity
The ratio of the mass of water vapor in the air at a given temperature to the maximum mass of water vapor in the air could hold at that temperature, expressed as a percent.
D. greenhouse effect
Which certain gases (principally water vapor, carbon dioxide, and methane) trapped heat that radiates from earth.
E. Parts per million
The number of molecules or Adams of a substance in next year for every 1 million molecules or Adams in that mixture
The temperature is the same at 1:00 PM on two consecutive days. For a person who is working outside, however, the second day feels cooler than the first day. On which day was a relative humidity higher
First day
A child decides to keep his goldfish outside in a small bowl. He has to add water every day to keep the board for. And two consecutive days people, the temperature and are very similar. But on the first day the relative humidity is 90%, wall on the second day is 60%. And which day with the child add more water to the goldfish bowl
The second day
If you put a glass of water outside win the relative humidity is 100% how quickly will the water evaporate?

Supposed astronomers found another solar system in which there was a son just like our son. Suppose further that a planet in this new source system was just as far from it son as earth is from our son. Since the vast majority of energy that planets get come from their sons, is it reasonable to assume that the new planet would have roughly the same average temperature is the dad of the earth? Why or why not?
No, the planets temperature depends on the ratio of gases in the plant atmosphere
What makes up the majority of the air max out?
Nitrogen
Do we exhale more carbon dioxide or more oxygen
Oxygen
Do the data indicate any significant global warming
No

Suppose you had a sample of air in which the concentration of nitrogen oxides is 0.023%. What was the concentration of nitrogen oxides be if you expressed it in ppm?
230 ppm
See you today, or was it clean or 30 years ago
It’s clear today
What is the cost/benefit analyst?
Is benefit greater than the cost
What does a cow like converted do in a car
It turns carbon monoxide into carbon dioxide
What does a scrubber do in a smokestack?
Cleans the air out of sulfur oxides
Why is the ozone layer not considered toxic
