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...

A spray can containing a propellant gas at twice atmospheric pressure (202 kPa) and having a volume of 119.00 cm is at 27°C. It is then tossed into an open fire. (Warning: Do not do this experiment; it is very dangerous.) When the temperature of the gas in the can reaches 195°C, what is the pressure inside the can? Assume any change in the volume of the can is negligible. SOLUTION Conceptualize Intuitively, you should expect that the pressure of the gas...

Please help
The light beam in the figure passes through a polarizer whose transmission axis makes an angle phi with the vertical. The beam is partially polarized and partially unpolarized, and the average Intensity S bar_0 of the incident light is the sum of the average intensity S bar_0, polar of the polarized light and the average intensity S bar_0, unpolar of the polarized light: S bar_0 = S bar_0, polar + S bar_0, unpolar. The intensity S bar of...

I need help with all parts of question one so any help on any
question is very much appreciated please help!!!!
In p - V phase diagrams, the slope. (partialdifferential p/partialdifferential V)_T, n, along an isotherm is never positive. Why? Regions where (partialdifferential p/partialdifferential V)_T, n = 0 represent equilibrium between two phases; volume can change with no change in pressure, as when water boils at atmospheric pressure. We can use this to determine the temperature, pressure, and volume per...
