Question

10 respuestas múltiples 1 punto which phase(s) of matter have particles arranged in a regular pattern? gas solid liquid 11 elección múltiple 1 punto which of the following describes gas pressure? the collisions of the particles with the walls of the container the size of the container the number of particles the average kinetic energy of the particles 12 fórmula 1 punto convert 3.887 grams to pounds. use 1 pound = 450 g. express your answer with 2 decimal places. respuesta

Explanation:

Step1: Recall particle arrangement in phases

In solids, particles are arranged in a regular pattern. In liquids, particles are close - packed but not in a regular pattern. In gases, particles are far apart and move freely.

Step2: Answer question 10

The phase of matter with particles arranged in a regular pattern is solid.

Step3: Recall gas pressure concept

Gas pressure is caused by the collisions of gas particles with the walls of the container.

Step4: Answer question 11

The description of gas pressure is the collisions of the particles with the walls of the container.

Step5: Set up conversion formula

We know that to convert grams to pounds, we use the conversion factor. Let $x$ be the mass in pounds. The formula is $x=\frac{3.887}{450}$.

Step6: Calculate the value

$x=\frac{3.887}{450}\approx0.01$

Answer:

1. Solid
2. The collisions of the particles with the walls of the container
3. 0.01
