A 2.0 kg bar of copper is heated at atmospheric pressure so that its temperature increases from 20°C to 50°C. (a) What is the work done on the copper bar by the surrounding atmosphere? SOLUTION Conceptualize This example involves a solid, whereas the preceding two examples involved liquids and gases. For a solid, the change in volume due to thermal expansion is very small. Categorize Because the expanslon takes place at constant atmospheric pressure, we categorize the process as isobaric...
