Chapter 8, Problem 8.115GP

Interpretation Introduction

Interpretation:

The change in atmospheric ${\text{CO}}_{\text{2}}$ level by a shift to corn-based ethanol or some other biomass based fuels should be determined.

Concept Introduction:

Greenhouse Effect: When the solar radiation reaches the earth’s atmosphere, some of the radiations gets reflected and some of the radiations are absorbed by earth’s surface. This energy is converted into heat and radiate back towards space. Some of these are trapped by green-house gases when going up to the atmosphere and this will heat up the earth’s atmosphere.

Greenhouse Gases:

• ${\text{CO}}_{\text{2}}$
• ${\text{CH}}_{\text{4}}$
• ${\text{N}}_{\text{2}}\text{O}$
• ${\text{H}}_{\text{2}}\text{O}$
• $\text{HCl}$

The most important green-house gas is water vapor.

If the amount of green-house gases in the atmosphere become too high, then the temperature will increase and the planet become warmer and the process is called as global warming.
