the Second Law of Thermodynamics requires that any heat engine exhaust waste heat, labeled QC in Figure 4.20, into the environment. This waste heat, sometimes referred to as thermal pollution, can have significant negative effects on the environment. Locate at least two newspaper or magazine articles within the last 10 years describing either the negative effects of waste heat from a particular source or measures taken to reduce the effects of waste heat from a particular source on the environment. Post links to the articles, or references if they are not available online, and provide a short summary of the contents of the articles
