This week, we learned about the motion of particles in solids, liquids, and
gases, how energy and heat affect the motion of particles, and the different
motions of particles and thanks to
Eureka! and Mr. Abud I came to enjoy the dancing of the "little lumps". First, we learned about the
different motions of particles. There are three types :
translational
motion, rotational motion, and vibrational motion.
Translational motion is the motion of particles moving side to side. Rotational motion is the motion
of particles moving from one point around and back to its initial point just like a ball would.Vibrational
motion is the motion of particles moving through particles. Mr. Abud brought out a block of dry ice and showed us that the ice was turning into steam immediately. This introduced
sublimation. Sublimation is the process of matter turning from a solid to a gas without turning into a liquid. After showing us this, Mr. Abud told our groups to draw particle diagrams of what the particles would look like before and after. All of our diagrams looked the same but we did not know how to show movement. We came to the conclusion that our "whoosies" would be arrows and that the length of the arow would represent the speed of the particles. We were also reintroduced to vocabulary such as rigid, meaning that they hold their own form and shape, and fluidity, meaning that the
particles have more ability to flow and move. Liquids and gases are fluid. A liquid cannot hold its own shape except when it holds the shape of
the container it's in.Gases
move faster than liquids and move greater distances.The motion of the particles in these three states of matter
vary because of how heat affects the motion of these particles. Heat is a form of energy transfered through heating. Heat makes the
particles move faster, therefore making a substance more less
viscous, meaning
that the particles become less resistant to move. The more heat the substances have,
the more energy they receive to put the particles in motion. Therefore, if solid, liquid, and gas
particles are heated, then the particles move faster with greater energy at
greater distances at this rate with greater energy. Also, what affects the motion of
particles is temperature. Temperature is the measurement of the average amount
of energy for all particles in a system. This means that the greater the
temperature, the greater the amount of heat and energy. So, a greater
temperature gives more heat and energy for the particles in any state of matter
to move faster. The relationship between
these three states of matter is that since the motion
of their particles vary, their densities will too. Since a solid
is rigid and the particles stay closer together they have the greatest density since the space between
the particles is less than that of liquids and gases. Liquids, though, have
lesser densities than solids, but densities greater than gases. Since the motion
of the particles in a liquid are quicker and the particles move in different
directions, the space between them is greater, therefore, the density is lesser.
Gases have the least density because the space between their particles is the
greatest since the particles can move faster than the particles of a solid and
liquid. Although it seems very complicated written out, I understand it easily! This week was pretty fun and I got many of the questions I was asking myslef on monday answered. Except one... Where in the world did Mr. Abud buy dry ice???
