Question

  1. at 47°c, a gas has a pressure of 140 kpa. the gas is cooled until the pressure decreases to 105 kpa. if the volume remains constant, what will the final temperature be in kelvins? p1 = 140 kpa t1 = p2 = 105 kpa t2 =

Explanation:

Response

Explicación:

Paso 1: Convertir la temperatura inicial a Kelvin

$T_1=(47 + 273)K=320K$

Paso 2: Aplicar la ley de Gay - Lussac (constante volumen)

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$, despejando $T_2$ tenemos $T_2=\frac{P_2T_1}{P_1}$

Paso 3: Sustituir valores

$P_1 = 140kPa$, $T_1 = 320K$, $P_2 = 105kPa$
$T_2=\frac{105kPa\times320K}{140kPa}=240K$

Respuesta:

$240K$
