Question

Which of the following apply to gases. Select all that apply. Gas collisions are elastic. Gases mix faster than solids or liquids. Gases with larger molecular weights diffuse slower than gases with lower molecular weights. Gases with larger molecular weights diffuse faster than gases with lower molecular weights. Gas particles can move like solids and liquids along with translational motion.

Answer 1

Gas collisions are elastic. Gases mix faster than solids or liquids. Gases with larger molecular weights diffuse slower than gases with lower molecular weights.

Answer 2

-Gas collisions are elastic

- Gases mix faster than solids or liquids-

Gases with larger molecular weights diffuse slower than gases with lower molecular weights.

Step-by-step explanation:

Matter is any substance that has weight and occupy space. There are three classes of matter. Theses are solid, liquid and gas.

Under Kinetic Theory of Gas

1. Gases move randomly in a straight line, thereby colliding with themselves and the walls of their containers

2. The collision of a gas molecule are perfectly elastic

3. temperature is a measure of average kinetic energy

Bearing this at the back of our minds, we can say that the following from the option applies to gases

-Gas collisions are elastic

- Gases mix faster than solids or liquids-

Gases with larger molecular weights diffuse slower than gases with lower molecular weights.

And these are not true

Gases with larger molecular weights diffuse faster than gases with lower molecular weights. Gas particles can move like solids and liquids along with translational motion.
