A gas cylinder of volume 26 liters contains an ideal gas at temperature 27 degrees C and pressure 1920 kPa. Some of the gas leaks until the pressure falls to 1500 kPa. How many moles of gas leaked, assuming that the temperature remains constant during this process?
use the inverse square law to display that in space shuttle territory, 200 kilometers above earth's surface, the force of gravity on a shuttle is about 94 percent of that at earth's surface.
What is final total energy of the system
