Question 41 (2 points) Read the following scenario and answer the questions Global climatic change has been a controversial topic. However, almost a nitrous oxide, ozone, h due to rapid i rising standards of living in dioxide temperatures by 3 to 10 degrees Fahrenheilt by 2100 scientists agree that gases contribute to global climate change. Carbon dioxide, methane, and water vapor are the main culprits. These ctivities, chief among them the tapping and burning of fossil fuels for energy, dramatically in our atmosphere in the last 300 years, tly increase greenhouse gases in our atmosphere. with ation. of carbon dloxide and other greenhouse gases are expected to continue to rise. If unchecked, it is predicted that carbon ury and double again by the end of the century, Computer models have shown that this rise aione could raise Earth's 2) Hydrogen-containing compounds trap the most heat. 3) water is a good conductor of electricity.

Explanation / Answer

Answer : The ionic bonds holding water vapor together help it trap heat. Explanation : the bonds present in water vapor or carbondioxide are loose enough to vibrate when radiation pass through it and reflects to the other molecule which helps in retaining the heat around the surface. In nitrogen and oxygen molecules the bonds are tight and cannot contribute to greenhouse effect.
