Question

un gas a 18 grados centígrados y 750 mm de hg ocupa un volumen de 150 centímetros cúbicos Cuál será su volumen a 65 grados centígrados si se mantiene constante la presión​

Answer 1

Respuesta:

V1 P1 T2 = V2 P2 T1

K = ºC  + 273

V1 = 200 L

T1 = 95 + 273 = 368 K

P1 = 782 mmHg

V2 = ?

T2 = 65 + 273 = 338 K

P2 = 800 mmHg

V2 = 200 L x 782 x 338 K

      ````````````````````````````

        800 mmHg x 368 K

V2 = 179,56 L

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

SI SE TRANSFORMA LA PRESION DE mmHg a atm

V1 = 200 L

T1 = 95 + 273 = 368 K

P1 = 782 mmHg / 760 = 1.028 atm

V2 = ?

T2 = 65 + 273 = 338 K

P2 = 800 mmHg / 760 = 1.052 atm

V2 = 200 L x 1.028 atm x 338 K

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

        1.052 atm x 368 K

V2 = 179.50 L
