Understanding States of Matter

What is the most basic definition of matter?

• Anything that has mass and volume

• Anything that can be seen and touched

• Anything that is made of energy

• Anything that has color and shape

Which of the following is NOT a state of matter?

• Solid

• Plasma

• Liquid

• Gas

How do particles in a solid behave?

• They move freely and quickly

• They vibrate in place

• They slide past each other

• They rotate around each other

What is the main characteristic of gas particles?

• They vibrate in place

• They are organized in rows

• They are tightly packed

• They move at high speeds

What happens to intermolecular forces as particles move further apart?

• They become stronger

• They become weaker

• They turn into chemical bonds

• They remain unchanged

Which state of matter has the strongest intermolecular forces?

• Solid

• Liquid

• Gas

• Plasma

What effect does adding heat have on the motion of particles?

• It increases their motion

• It has no effect on their motion

• It decreases their motion

• It stops their motion

In which state of matter are particles completely free to move?

• Solid

• Liquid

• Gas

• Plasma

What limits the freedom of movement of particles in a solid?

• High energy levels

• Strong intermolecular forces

• Low energy levels

• Weak intermolecular forces

How do particles in a liquid behave compared to those in a solid?

• They can slide past each other

• They are completely free to move

• They are more tightly packed

• They have less freedom to move
