Question

1. a 40.0 l tank of ammonia has a pressure of 12.7 kpa. calculate the volume of the ammonia if its pressure is changed to 8.4 kpa while its temperature remains constant.

Explanation:

Step1: Identificar la ley de Boyle

Para un gas a temperatura constante, $P_1V_1 = P_2V_2$.

Step2: Asignar valores

$P_1 = 12.7\ kPa$, $V_1 = 40.0\ L$, $P_2 = 8.4\ kPa$.

Step3: Despejar $V_2$

$V_2=\frac{P_1V_1}{P_2}$.

Step4: Calcular $V_2$

$V_2=\frac{12.7\ kPa\times40.0\ L}{8.4\ kPa}\approx60.5\ L$.

Answer:

$60.5\ L$
