Find the change of internal energy and enthalpy of nitrogen
What is the change of internal energy and enthalpy of 4 kg nitrogen as it changes from 50oC and 100kPa to 100oC and 200kPa? Does the pressure at the beginning and end of this process have any effect on the results?

An oil pipeline was constructed to transport an oil with SG = 0.8 for a distance of 10 miles. The country was hilly, so the line made many ups and downs. These may be considered equivalent to 10 rises of 200 ft, followed by descents of 200 ft.
Calculate the electric field at the center of a square 53.0 cm on a side, if one corner is occupied by a +48.0 µC charge and the other three are occupied by -22.0 µC charges. (Assume the center of the square is at the origin and the po
