Under which of the following conditions do REAL gases behave most like IDEAL gases?

Low pressure and high temperature

High pressure and high temperature

High pressure and low temperature

Low pressure and low temperature

A sample of gas is contained in a closed container under 2 atm of pressure. According to kinetic molecular theory, what causes this pressure?

The gas molecules are colliding with the walls of the container, exerting a force on the container.

The gas molecules are colliding with each other, exerting a force on each other.

The gas particles are chemically reacting with each other releasing energy.

The gas molecules are attaching to the walls of the container, pulling it inward.

Which of the following is not one of the postulates of the Kinetic Molecular Theory for ideal gases?

The particles attract and then repel each other

The collisions between particles are elastic.

The particle size is very small compared to the space between the particles.

The particles are in constant random motion.

Which of the following explains the change in pressure when volume increases?

As the volume increases, the particles have more space to move and collide less with the walls , causing pressure to decrease.

As the volume increases, the particles slow down, causing less collisions and less pressure.

As the volume increases, the particles speed up, causing more collisions and more pressure.

As the volume increases, the particles have more space to move and collide less with the walls , causing pressure to increase.

Which is a quality that only gasses display

Spread out to fill all available space

Take the shape of their container

Gas molecules can easily be compressed because ___________.

gas molecules follow the shape of the container

Pressure is caused by ______.

gas molecules colliding with surfaces of the container.

gas molecules colliding with each other.

gas molecules reacting with each other.

Which container will have lower pressure?

they both have the same pressure

Pick the best answer to explain all properties of gases....

They're fluids Can be compressed Lots of space between particles

They're fluids Can be compressed Little space between particles

They're solids Can be compressed Lots of space between particles

They're fluids Cannot be compressed Lots of space between particles
