Question

5 formula 1 punto determine the pressure, in atm, when a constant - volume of gas at 0.6 atm is heated from 19.8 °c to 291.8 °c. respuesta 1.2 6 formula 1 punto a 9.0 l tank of ammonia has a pressure of 163.5 kpa. calculate the volume of the ammonia if its pressure is changed to 39.3 kpa while its temperature remains constant. round to 1 decimal place. respuesta 7 decisión múltiple 1 punto which phase of matter has particles that vibrate in fixed positions? gas solid liquid

Explanation:

5.

Step1: Convert temperatures to Kelvin

$T_1 = 19.8 + 273.15=292.95$ K, $T_2 = 291.8+ 273.15 = 564.95$ K

Step2: Apply Gay - Lussac's law ($\frac{P_1}{T_1}=\frac{P_2}{T_2}$)

$P_2=\frac{P_1T_2}{T_1}$
$P_2=\frac{0.6\times564.95}{292.95}\approx1.2$ atm

Step1: Identify Boyle's law ($P_1V_1 = P_2V_2$)

$P_1 = 163.5$ kPa, $V_1=9.0$ L, $P_2 = 39.3$ kPa

Step2: Solve for $V_2$

$V_2=\frac{P_1V_1}{P_2}$
$V_2=\frac{163.5\times9.0}{39.3}\approx37.4$ L

In solids, particles are closely packed and vibrate in fixed positions due to strong intermolecular forces.

Answer:

$1.2$
