States Of Matter - Solids, Liquids & Gases | Properties of Matter | Chemistry | FuseSchool
Summary
TLDRThis educational video explains the three states of matter: solid, liquid, and gas. Solids, like a computer, have closely packed, immobile particles, making them rigid with a fixed shape and volume. Liquids, such as water, have closely packed particles that can move, allowing flow but retaining volume, despite the lack of a fixed shape. Gases, exemplified by helium, have widely spaced particles, making them compressible and shapeless, filling any container they occupy.
Takeaways
- 🧊 The three states of matter are solid, liquid, and gas.
- 💻 Solids have particles closely packed in fixed positions, making them rigid with a fixed shape and volume.
- 💧 Liquids have particles closely packed but can move around each other, allowing flow but maintaining a fixed volume.
- 💡 A common misconception is that liquids do not have a fixed volume, but they do.
- 🍺 An example to illustrate liquid volume is ordering a pint of beer, which cannot be turned into two pints by changing containers.
- 🌬️ Gases have particles far apart, making them compressible and fill the entire space available without a fixed shape or volume.
- 🎈 Helium is an example of a gas used in party balloons due to its low density and unreactive nature.
- 🔍 The properties of each state of matter are dependent on how the particles are packed.
- 📏 Solids cannot be compressed or squashed due to their tightly packed particles.
- 🌊 Liquids do not have a fixed shape but can take the shape of their container while maintaining volume.
- 🌀 Gases are highly compressible and can be squashed or compressed easily.
Q & A
What are the three states of matter?
-The three states of matter are solid, liquid, and gas.
What is an example of a solid?
-An example of a solid is a computer.
How are the particles in solids arranged?
-The particles in solids are closely packed in fixed positions and cannot move around.
What are the characteristic properties of solids?
-Solids are rigid, cannot be squashed or compressed, have a fixed shape, and a fixed volume.
What is an example of a liquid?
-An example of a liquid is water.
How are the particles in liquids arranged compared to solids?
-The particles in liquids are closely packed but not as closely as in solids, allowing them to move around each other.
What are the characteristic properties of liquids?
-Liquids are not rigid, cannot be squashed or compressed, do not have a fixed shape, but have a fixed volume.
Why do liquids not have a fixed shape but do have a fixed volume?
-Liquids do not have a fixed shape because their particles can move over one another, but they have a fixed volume because the number of particles is constant and they occupy space.
What is an example of a gas?
-An example of a gas is helium, which is used in party balloons.
How are the particles in gases arranged compared to solids and liquids?
-The particles in gases are far apart and not closely packed, allowing gases to be compressible and to expand to fill any space.
What are the characteristic properties of gases?
-Gases are not rigid, can be squashed or compressed, do not have a fixed shape, and do not have a fixed volume; they fill the entire space they are in.
Why is it incorrect to say that liquids do not have a fixed volume?
-It is incorrect because, despite not having a fixed shape, liquids maintain a fixed volume as the total space occupied by the particles does not change.
How do the properties of matter relate to the arrangement of its particles?
-The properties of matter are directly related to how closely packed the particles are. In solids, they are tightly packed, in liquids they are less so but still closely, and in gases, they are far apart.
Outlines
🔬 States of Matter
This paragraph introduces the three fundamental states of matter: solid, liquid, and gas. It explains that the properties of these states are determined by how closely the particles are packed together. Solids have closely packed particles in fixed positions, making them rigid with a fixed shape and volume. Liquids also have closely packed particles but with more freedom to move, resulting in a lack of rigidity and a variable shape but a fixed volume. Gases have particles that are far apart, allowing them to be compressed, and they do not have a fixed shape or volume, filling the space available.

Highlights
The three states of matter are solid, liquid, and gas.
Solids have particles closely packed in fixed positions.
Solids are rigid, cannot be squashed or compressed, and have a fixed shape and volume.
An example of a solid is a computer.
Liquids have particles closely packed but can move around each other.
Liquids are not rigid, do not have a fixed shape, but have a fixed volume.
Water is given as an example of a liquid.
Liquids can flow and fill different containers to their volume.
Gases have particles that are far apart and not closely packed.
Gases are not rigid and can be squashed or compressed.
Gases do not have a fixed shape or volume and fill the entire space available.
Helium is an example of a gas used in party balloons.
The properties of matter depend on how particles are packed.
Solids cannot flow, unlike liquids and gases.
Liquids take the shape of their container but maintain their volume.
Gases expand to fill any space, regardless of shape or volume.
The concept that liquids do not have a fixed volume is a common misconception.
The video explains the characteristics of each state of matter in detail.
Transcripts
in this video you are going to learn
what the three states of matter are some
examples of each state of matter the
characteristic properties of the three
states of
matter the three states of matter are
solid liquid and gas let us look at
solids
an example of a solid is your computer
the properties of solids depend on how
the particles in solids are packed in a
solid the particles are closely packed
in fixed positions and cannot move
anywhere so solids are rigid cannot be
squashed or compressed have a fixed
shape and a fixed volume they cannot
flow now let us look at liquids an
example of a liquid is water
just as with solids the properties of
liquids depend on how the particles in
liquids are
packed in a liquid the particles are
again closely packed but not as closely
packed as in
solids so this means the particles in
liquids can move around each other so
liquids are not rigid but because their
particles are closely packed as in
solids they cannot be squashed or
compressed they do not have a fixed
shape but they do have a fixed volume
Beware with that one as many students
think because liquids do not have a
fixed shape they do not have a fixed
volume either but they are wrong if
someone orders a pint of beer they
cannot make it two pints by pouring it
into different
containers as you know liquids can
flow finally let us look at gases an
example of a gas is helium
this is the gas imp party balloons
because it is less dense than air and
unreactive again as with solids and
liquids the properties of gases depend
on how the particles in gases are packed
unlike solids and liquids the particles
in gases are not closely packed they're
far
apart as a result gases are not rigid
and can be squashed or
compressed they do not have a fixed
shape no fixed volume they fill the
whole Space they are
in
