Question

un gas tiene presion de 800mmhg ,un volumen de 675ml y una temperatura de 2000°c, calcukar la prrsion a 300°c con volumen de 1,8ml

Answer 1

LEY GENERAL DE LOS GASES:

V1  x  P1  =  V2  x  P2
````````````     ``````````````
      T1                T2

P1 = 800 mmHg/ 760 = 1.05 atm
V1 = 615 / 1000 = 0.615 L
T1 = 2000 ºC + 273 = 2273 K

P2 = ?
V2 = 1.8 / 1000 = 0.0018 L
T2 = 300 ºC + 273 = 573 K

P2 = 0.615 L  x  1.05 atm  x  573 K
        ``````````````````````````````````````````
                  0.0018 L x  2273 K

P2 = 90.44 atm
