The nature of gas
Perfectly elastic
All collisions between particles in a gas are what?
intermolecular attractions
How are liquid molecules attracted to each other?
vibrate only
Do solids flow freely or vibrate only?
when a substance changes from a solid to a gas without going through the liquid state.
What is sublimation?
Energy an object has because of its motion.
What is Kinetic Energy?
Gas Particle
What particle is considered to be small, hard spheres with an insignificant volume?
The heat makes the average kinetic energy speed up the process.
What those heat do the the average kinetic energy during evaporation?
the temperature the solid turns into a liquid.
What is the melting point do?
Dry ice would be considered a sublimes substance because it goes from a solid to a gas right away.
Would dry ice be considered a sublimes substance?Why?
When there is no particles and only empty space
What is a vacuum?
barometer
With what tool can we measure pressure?
The process can continue endless in a closed environment causing an equilibrium. Making the environment have the same amount of water in constant changing state of vapor and liquid.
What happens in a closed environment with vapor pressure?
When the freezing and melting point are at the same temperature that is known as an equilibrium.
What happens when the melting point and freezing point collide?
Temperature and pressure
What those a phase diagram use to compare the states of matter?
the pressure of a vapor in contact with its liquid form.
What is vapor pressure?
A group of gas particles collide at the same time with an object creating pressure and making it move.
Describe how gas pressures can make an item move?
occurs when the liquid boils and turns into vapor because the vapor pressure is equal to the external pressure.
What is the boiling point?
lacks an ordered internal structure.
What is an amorphous solid?
the set of conditions where all three states of matter exist in equilibrium with each other.
What those the triple point mean in a phase diagram?
two or more different molecular forms of the same element in the same physical state.
What is a allotrophes?
Liquids and solids
Which two states of matter are the most complex?
The more heat you add to the particle only speeds up the process helping the particles escape faster. You can get an easier burn from steam than hot water because of this. Touching your skin at a faster rate.
Can you get an easier burn from hot water or steam?Why?
When an amorphous solid break, the fragments have irregular angles and jagged edges.
What happens when an amorphous solid breaks?
In higher pressures the boiling points increases and the melting point decreases.
Those the melting point and boiling point increase or decrease at higher pressures?
used in order to compare the temperature and pressure of solids, liquids, and gasses, all in one.
What is a phase diagram?
