A balloon contains 5 L of oxygen at a pressure of 90 kPa. How much oxygen will the balloon contain if the pressure is lowered to
laila [671]
Answer is: volume will be 6,7 L.
Boyle's Law: the pressure volume law - <span> volume of a given amount of gas held  varies inversely with the applied pressure when the temperature and mass are constant.
p</span>₁V₁ = p₂V₂.
90 kPa · 5 L = 67 kPa · V₂.
V₂ = 90 kPa · 5 L / 67 kPa.
V₂ = 6,7 L, but same amount of oxygen.

two sides of a triangle have the following measures . Find The range of possible measures for the tird side
crimeas [40]
To find the third side you would use Pythagorean theorem which is a²+b²=c². 

A and B being the 2 legs and C being the hypotenuse.
 
Example: ( sorry for the really odd not really a triangle, triangle...)
  |  \
6|     \  ?                    6²+9²=C²
  |_______              36+81=C²
        9                             117=C²
                               √117=10.8 (rounded) 

if you need to get the leg you just fill in the numbers.
