AKS 5 - States of Matter and Gas Laws

The electrical current in the tube generates the neon gas that glows in the dark.

Electrical energy excites the neon atoms. They spin faster in the tube producing electromagnetic waves that we see as colors.

Neon atoms accelerate once electrical energy is turned on to the tube. The faster the atoms move in the tube, the brighter the glow we see.

Electrical energy accelerates the electrons in the neon gas. The gas ionizes and becomes plasma, containing both positive and negative ions.

The gaseous and plasma states are electrically neutral.

The gaseous state is electrically positive, while the plasma state is electrically negative.

The gaseous state is electrically negative, while the plasma state is electrically negative.

The gaseous state is electrically neutral, while the plasma state can be either electrically positive or negative.

solids have a more ordered arrangement of atoms than liquids and gases.

in solids molecules move faster than in liquids or gases.

solids have less internal energy than liquids and gases.

solids have the least orderly internal structure.

As the phase changes occur, the freedom of motion of the particles increases.

As the phase changes occur, the freedom of motion of the particles decreases.

As the phase changes occur, the freedom of motion of the particles compresses.

As the phase changes occur, the freedom of motion of the particles is constant.

Definite shape and low energy particles

No definite shape and no definite volume

No definite shape and high energy particles

No definite shape and medium energy particles

because there are fewer molecules in the balloon outside

because the air pressure is significantly higher when it is colder

because the molecules in the balloon have slowed down with the temperature

because the molecules shrink in size when exposed to the colder, outside air

Pressure will expand a gas, enlarging its volume and reducing its density and concentration of particles.

Pressure will magnify a gas, developing its volume and multiplying its density and concentration of particles.

Pressure will compress a gas, reducing its volume and giving it a greater density and concentration of particles.

Pressure will accelerate a gas, extending its volume and allowing a smaller density and concentration of particles.

As the volume of a contained gas expands, its pressure concentration of particles will increase.

As the volume of a contained gas extends, its pressure concentration of particles will increase.

As the volume of a contained gas decreases, its pressure concentration of particles will increase.

As the volume of a contained gas compresses, its pressure concentration of particles will decrease.

All the balloons would shrink.

All the balloons would expand.

The balloon in the ice water would expand.

The balloon in the 65°C water would expand.

The increased pressure, pushed the molecules closer together, and caused the marshmallow to shrink.

The decreased pressure, pushed the molecules closer together, and caused the marshmallow to shrink.

The increased pressure, allowed the molecules to spread apart, and caused the marshmallow to grow larger.

The decreased pressure, allowed the molecules to spread apart, and caused the marshmallow to grow larger.

As the temperature extends, the kinetic energy of the particles decreases.

As the temperature increases, the kinetic energy of the particles increases.

As the temperature decreases, the kinetic energy of the particles increases.

As the temperature intensifies, the kinetic energy of the particles decreases.
