P*V=n*R*T where p is the pressure, v the volume in L, n the quantity in moles, R a standard number that should be given and T the temperature in Kelvin R=8.32 (usually) T(in K)=273+T(in Celsius) so T=296K P*V=n*R*T P=n*R*T/V P=0.4*8.32*296/0.2
The Solar System moves through the galaxy with about a 60° angle between the galactic plane and the planetary orbital plane. The Sun appears to move up-and-down and in-and-out with respect to the rest of the galaxy as it revolves around the Milky Way
Inside the mouth, these cells are joined together in a sheet. Why are they scattered here? They are scattered here because we disrupted there original form by scrapping them off our mouths and smearing them on the slide.
