Question
- 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 =
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:
$240K$
