Question

Alguien que me ayude con estos ejercicios?

Answer 1

Ley general de los gases

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

3.  calcular T = ?

P1 = 2 atm
T1 =  27 ºC + 273 = 300 K
V1 = 6 L

P2 = 4 atm
T2 = ?
V2 = 15 L

T2 =   4 atm  ·  15  L  ·  300 K
        ``````````````````````````````````
                 2 atm ·  6 L

T2 = 1500 K

convertir K a ºC       ºC = K - 273

T = 1500 - 273 = 1227 ºC   respuesta E

4.  calcular presión

V1 = 4 L
P1 = 4 atm
T1 = 127 + 273 = 400 K

V2 = 16 L
T2 = 527 + 273 = 800 K
P2 = ?

P2 = 4 L  ·  4 atm  ·  800 K
        ``````````````````````````````
              16 L  · 400 K

P2 = 2 atm  respuesta A
