How does hydraulic fracturing differ from previously used techniques for the recovery of natural gas from the earth?
As weather balloons rise from the earths surface, the pressure of the atmosphere becomes less, tending to cause the volume of the balloons to expand. However, the temperatura is much lower in the upper atmosphere than at sea level. Would this temperatura effect tend to make such a balloon expand or contract? Weather balloons do, in fact, expand as they rise. What does this tell you?
What possible uses exist for the natural gas liquids that are removed from natural gas during its processing?
Describe what happens o the average kinetic energy of ideal gas molecules when the conditions are changed as follows: (a) The pressure of the gas is increased by reducing the volume at constant temperature. (b) The pressure of the gas is increased by increasing the temperature at constant volume. (c) The average velocity of the molecules is increased by a factor of 2.
What does “STP’ stand for? What conditions correspond to STP? What is the volume occupied by one mole of an ideal gas at STP
