Gases are in rapid motion, and they undergo elastic collisions with each other and the walls of the container; that is, momentum and energy is transfered not lost during collisions.
Gases expand spontaneously to fill any container
(rapid motion). Brownian motion of smoke particles (rapid motion).
Why does gas expand to fill its container?
Heating a gas increases the kinetic energy of the particles
, causing the gas to expand. In order to keep the pressure constant, the volume of the container must be increased when a gas is heated.
Do gases expand to fill their container?
Gases expand spontaneously to fill any container
(rapid motion). Brownian motion of smoke particles (rapid motion). In an insulated container gases do not slow down and eventually condense (elastic collisions). The gas molecule do not interact with each other except for colliding with each other.
Does liquid fill a container completely?
Unlike gases,
a liquid will not change its volume to spread out and completely fill a container
. There is enough intermolecular bonding
Will flow only sideways and down?
Definite means something does not change. The most important liquid to living things is water. This answer is the students' choice. … A
_______liquid______
will flow only sideways and down.
Why do solids not fill the entire container?
Because
the particles don't move
, solids have a definite shape and volume, and can't flow. Because the particles are already packed closely together, solids can't easily be compressed. … Powdered solids cannot take the shape of their container.
Do not expand to fill their containers?
The attraction between the particles in a
liquid
keeps the volume of the liquid constant. The movement of the particles causes the liquid to be variable in shape. Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume.
Why does a liquid fill the shape of a container but an ice cube does not?
Item AM057005: Liquid water takes the shape of a cup it is poured into but solid ice cubes do not,
because the molecules of liquid water can easily move past one another but the molecules of solid ice cannot
.
What is the hardest state of matter?
As the temperature continues to drop, the matter forms a solid. Due to the solid's low kinetic energy, particles have no “time” to move around, the particles have more “time” to be attracted. Therefore,
solids
have the strongest intramolecular forces
Which state of matter can flow in all directions?
Gas
is described as a state of matter which diffuses freely in all directions and fills the entire space available, regardless of the quantity. A water-like fluid, that flows freely, having a definite volume but no permanent shape, is called liquid.
What has fixed volume but no fixed shape?
Liquids
have a fixed volume but no fixed shape. Gases have no fixed volume and no fixed shape. Gases expand to fill the space available. They can also be compressed into a very small space.
Can solids be compressed?
A solid is something that can hold its own shape and
is hard to compress
(squash). The particles in most solids are closely packed together. Even though the particles are locked into place and cannot move or slide past each other, they still vibrate a little.
Are there spaces in between the particles of liquid and gas?
A gas and a liquid will change shape to fit the shape of their container. A gas will change volume to fit the volume of the container. … The particles in a liquid usually are still touching but there are some spaces between them.
The gas particles have big distances between them
.
What will happen to the volume of the container when a gas can expand?
Increasing the amount of space available will
allow the gas particles to spread farther apart, but this reduces the number of particles available to collide with the container, so pressure decreases. … As more air goes in, the gas molecules get packed together, reducing their volume.
