Green: nm 495–570. Yellow: nm 570–590. 590–620 nm for orange. Red: 620-750 nm (400–484 THz frequency)

Solids' molecules are strongly attracted to one another. As a result, the molecules are barely moving and tightly packed. Because of this, shape and volume are fixed.

The forces of attraction and repulsion in liquids are comparable. Compared to the solid state, they move a little bit more. They then assume the shape of the container while still having a fixed capacity.

The attraction forces between the molecules in gases are quite weak. They move quite freely and grow in an effort to fill as much space as they can. Consequently, their volume and shape vary (adopt the shape of the container).

Identify the situations that have an unbalanced force. Check all that apply. A baseball speeds up as it falls through the air. A
viktelen [127]
<span>A baseball speeds up as it falls through the air.
Yes.  Forces on the balloon are unbalanced. 
The balloon is speeding up, so we know that the downward force
of gravity is stronger than the upward force of air resistance.

A soccer ball is at rest on the ground.
No. The ball is not accelerating, so we know that the forces on it
are balanced.
The downward force of gravity on the ball and the upward force
of the ground are equal.


An ice skater glides in a straight line at a constant speed.
No. The skater's speed and direction are not changing, so he is not
accelerating.  That tells us that the forces on him are balanced.

A bumper car hit by another car moves off at an angle.
Yes.  The direction in which the car was moving changed. 
That's acceleration, so we know that the forces on it are unbalanced,
at least at the moment of impact. 

A balloon flies across the room when the air is released.
Yes.  The balloon was not moving. But when the little nozzle was
opened, it started to zip around the room.  So its speed changed.
And, as it goes bloozing around the room, its direction keeps changing too. 
There's a whole lot of acceleration going on, so we know the forces on it
are unbalanced.</span>
