24. Explain each of these observations a A car parked in a sunny location may become hot enough to endanger the lives of pets or small children left in it. b. Clear Winter nights tend to be colder than cloudy ones. c. A desert shows much wider daily temperature variation than a moist environment. d. People wearing dark clothing in the summertime put themselves at a greater risk of heatstroke than those wearing white clothing 25. Draw the Lewis structure and name the molecular geometry for each molecule. Formula HAS OCI NO oxygen is central atom (nitrogen is the central atom Lewis structure Molecular geometry Table 3.3 Climate change and Ozone Depletion: A Comparison Climate Change Ozone Depletion region of primarily the troposphere the stratosphere atmosphere major players H:0, CO, CH, and N20 O, O, and CFCS Molecules absorb IR radiation. This Molecules absorb UV radiation. This causes interaction causes them to vibrate and return heat with radiation one or more bonds in the molecule to energy to the Earth break. Greenhouse gases are increasing in CFCs are causing a decrease in nature of concentration. In turn, this is trapping concentrations of O3 in the stratosphere. In problem more heat, causing an increase in the turn, this is causing an increase in the UV average global temperatures radiation at the surface of the Earth
