Once enough heat is added to a liquid to drive its vapor pressure to the level of atmospheric pressure, the liquid begins to boil. How much heat needs to be added depends on the characteristics of the substance. But what if the substance is not pure water, but instead a solution in whic...
How to calculate vapor pressure using enthalpy of vaporization A sample of gas with an initial volume of 2.0 L and a pressure of 3.0 atm is compressed to a volume of 1.5 L. What is the new pressure of the gas? Assume constant temperature and amount of gas. ...
The Clausius Clapeyron equation is a thermodynamic equation that relates the change in vapor pressure of a substance to its temperature. It is often used to calculate the vapor pressure of a substance at different temperatures, and can also be used to estimate the boiling poin...
General aviation pilots use this data to calculate the likelihood of carburetor icing and fog formation and estimate the height of cumuliform cloud bases. Increasing atmospheric pressure will raise the dew point. This means that if pressure increases, you must reduce the mass of water vapor per ...
How is temperature related to the physical change of a substance? How does the climate system connect with humidity? How is meteorology a part of geography? How does the polar jet stream affect temperature and precipitation? How do concentrations of water vapor in the atmosphere change?
Calculate the weight of waterthat has a volume equal to that of the buoy, using 62.4 pounds / ft-cubed as the density of water, as follows: 2 ft-cubed x 62.4 lbs / ft-cubed = 124.8 pounds / ft-cubed. Step 3 Note that the buoy, if held under water, displaces 124.8 pounds of ...
2. How did that water vapor to pass through it? Between water vapour molecules are very independent, adsorption of molecules. (The direction of movement of water vapor molecules will depend on the water vapor pressure and temperature on both sides), water vapor molecules will shift from one si...
As wind moves over the car in the tunnel, computers are used to calculate the drag coefficient (Cd). Wind tunnels are really nothing new. They've been around since the late 1800s to measure airflow over many early aircraft attempts. Even the Wright Brothers had one. After World War II,...
of this pesky algebra, you finally have an expression that assesses the catalytic efficiency, or enzyme efficiency, of a given reaction. You can calculate the constant directly from the concentration of enzyme, the concentration of substrate and the velocity of product formation by re-arranging to...
