Why is ground level ozone most likely to reach its highest concentrations on hot, sunny days during periods of heavy traffic in large cities?

Explain CFCs ?

Which of the following statements correctly describes the formation of the ozone hole over Antarctica during the months of spring? The reaction of CFCS and sunlight releases molecules of ozone; in spring, UV rays cause the ozone molecules to release chlorine atoms, which then react to break apart ozone molecules. The reaction of CFCS and sunlight releases atoms of chlorine; in spring, UV rays cause the CFCS to break down and release chlorine atoms, which then react to break apart ozone molecules. The reaction of CFCS and sunlight releases atoms of chlorine; in spring, UV rays cause the CFCS to break down and release chlorine atoms, which then react to break apart ad- ditional CFC molecules. The reaction of CFCS and sunlight releases atoms of chlorine; in spring, UV rays cause the CFCS to combine, and these newly formed molecules react to break apart ozone molecules.

1. What are the three main types of greenhouse gases, what are their respective characterization factors or global warming potential? 2. What is meant by the efficiency of a solar panel (PV) and what are the implications for a solar farm? 3. How is energy extracted from wind and what are the implications for a wind farm? 4. For a wind turbine, what is the impact of the wind speed on the electricity production and how does the design of the wind turbine dictate its efficiency? What control strategies can be used to optimise the performance of wind turbines? How can energy be extracted geothermally. Explain how geothermal energy can be utilised to contribute towards heat demand and what is the role of co-produced water. 5. 6.
