Question

14 formula 1 punto a container containing 7.3 l of a gas is collected at 255.1 k and then allowed to expand to 17.8 l. what must the new temperature be, in k, in order to maintain the same pressure? round to 1 decimal place. respuesta 377.8 15 elección múltiple 1 punto which of the following describes volume of a gas? the number of particles the average kinetic energy of the particles the size of the container the collisions of the particles with the walls of the container 16 elección múltiple 1 punto which phase of matter is represented by the diagram below?

Explanation:

Step1: Identify the gas - law formula

For a gas at constant pressure, we use Charles's law: $\frac{V_1}{T_1}=\frac{V_2}{T_2}$, where $V_1$ and $T_1$ are the initial volume and temperature, and $V_2$ and $T_2$ are the final volume and temperature.

Step2: Rearrange the formula to solve for $T_2$

$T_2=\frac{V_2T_1}{V_1}$

Step3: Substitute the given values

$V_1 = 7.3$ L, $T_1=255.1$ K, $V_2 = 17.8$ L. Then $T_2=\frac{17.8\times255.1}{7.3}$.
$T_2=\frac{4540.78}{7.3}\approx622.0$ K

The volume of a gas is the space it occupies, which is determined by the size of the container it is in. The number of particles refers to the amount of gas (moles), the average kinetic energy of the particles is related to temperature, and the collisions of particles with the container walls are related to pressure.

Answer:

$622.0$
