The molar volume of a gas at 0 °C temperature and 101.325 kPa is 22.414 m 3 /kmol. ... in the form of left-over dimensions – dimensional adjusters – that can ...
A temperature gradient is a physical quantity that describes in which direction and at what rate the temperature changes the most rapidly around a particular location. The temperature spatial gradient is a vector quantity with dimension of temperature difference per unit length. The SI unit is kelvin per meter (K/m).
A more physically informative version of such a law views empirical temperature as a chart on a hotness manifold. [ 43 ] [ 58 ] [ 60 ] While the zeroth law permits the definitions of many different empirical scales of temperature, the second law of thermodynamics selects the definition of a single preferred, absolute temperature , unique up to ...
These figures should be compared with the temperature and density of Earth's atmosphere plotted at NRLMSISE-00, which shows the air density dropping from 1200 g/m 3 at sea level to 0.125 g/m 3 at 70 km, a factor of 9600, indicating an average scale height of 70 / ln(9600) = 7.64 km, consistent with the indicated average air temperature over ...
where R is the ideal gas constant, T is temperature, M is average molecular weight, and g 0 is the gravitational acceleration at the planet's surface. Using the values T=273 K and M=29 g/mol as characteristic of the Earth's atmosphere, H = RT/Mg = (8.315*273)/(29*9.8) = 7.99, or about 8 km, which coincidentally is approximate height of Mt. Everest.
YouTube global head of family and children's content Malik Ducard admitted that "making the app family friendly is of the utmost importance to us", but admitted that the service was not curated all the time, and that parents had the responsibility to use the app's parental controls to control how it is used by their children (including ...
