Particle(s)

The video tutorial explains the role of molecules in forming matter and how the arrangement and movement of particles determine whether a substance is a solid, liquid, or gas. It also introduces elementary particles, which are the smallest indivisible components of matter.

What are molecules responsible for?

• Generating light

• Producing sound

• Creating energy

• Forming all matter

What determines if a substance is a solid, liquid, or gas?

• The color of the substance

• The size of the particles

• The temperature of the environment

• The arrangement and movement of its particles

Which of the following is NOT a state of matter?

• Plasma

• Gas

• Liquid

• Solid

What are elementary particles?

• Particles that are the smallest and cannot be divided further

• Particles that are only found in liquids

• Particles that can be divided into smaller components

• Particles that change state easily

Which of the following is true about elementary particles?

• They can be split into smaller parts

• They are only found in gases

• They are larger than molecules

• They are the building blocks of molecules
