WebThe ideal gas is defined as a gas which obeys the following equation of state: Pv = RT. The internal energy of an ideal gas is a function of temperature only. That is, u = u (T) Using the definition of enthalpy and the equation of state of ideal gas to yield, h = u + P v = u + RT. Since R is a constant and u = u (T), it follows that the ... WebCarbon dioxide is a colorless gas with a density about 53% higher than that of dry air. It is relatively nontoxic and noncombustible, but it is heavier than air and may asphyxiate by the displacement of air. When CO2 is solved in water, the mild carbonic acid, is formed. ...
