Question

15g de un gas cuyo comportamiento es ideal , se halla en un recipiente de 19,5l a 145grados centigrados si la temperatura se disminuye hasta 20 grados centigrados ¿cual es el volumen final ?

Answer 1

MASA Y PRESION SE CONSIDERAN CONSTANTES

V1  =  V2
````      `````
 T1      T2

V1 = 19.5 L
T1 = 145 + 273 = 418 K

V2 = ?
T2 = 20 + 273 = 293 K

V2 = 19.5 L  x  293 K
       ``````````````````````
                 418 K

V2 = 13.66 L

``````````````````````````````````````````````````````````````````````````````

NOTA SI LA TEMPERATURA DISMINUYE A 20 ºC ENTONCES SERÍA    -20 ºC

V1 = 19.5 L
T1 = 145 + 273 = 418 K

V2 = ?
T2 = -20 + 273 = 253 K

V2 = 19.5 L  x  253 K
       ``````````````````````
                 418 K

V2 = 11.80 L

Answer 2

Respuesta:

28 litros

Explicación:

Datos

T1: 15°C+273: 288°K

V1: 19.5 litros

T2: 145°C+273: 418°K

V2: ?

V2= 19.5L*418°K/288°K= 28 litros

V2: 28 litros
