Gases
This is a device that is used to measure atmospheric pressure.
What is a barometer?
When a liquid converts to gas
What is vaporization?
Useful for separating substances
What is sublimation?
The change of a Solid to Liquid at a set temperature.
What is a melting point?
An increase of kinetic energy.
What is an increase in temperature?
This occurs when particles of a warm liquid increases in kinetic energy.
What happens when vapor pressure increases?
When particles in a solid are arranged in a specific, repeating order, the solid is a(n) __________ solid.
What is crystalline?
Dry ice is a common example of
What is sublimation?
As particles move farther apart, potential energy _______.
What are increases?
Potential Energy speeds up the particles,which increases kinetic energy.
What causes the kinetic energy to increase?
the smallest group of particles within a crystal that retains the geometric shape of the crystal
What is a unit cell?
Evaporation only occurs at the surface of a liquid. Boiling occurs throughout. Boiling is associated with high temperatures. Evaporation can occur at any temperature at which matter is in the liquid state.
What is the difference between evaporation and boiling?
Kinetic energy is transferred without loss from one particle to another, and the total kinetic energy remains constant.
What happens during an elastic collision?
Bubbles of vapor form throughout the liquid, rise to the surface, an escape into the air.
What is Vaporization?
pure carbon/ Fullerene nanotubes.
What is the strongest material in the world?
This is the SI unit of pressure it represents a very small amount of pressure.
What is the Pascal (pa)?
The reduce in space between particles in a liquid.
What is intermolecular attractions?
a solid that is not a crystalline form and lacks an ordered internal structure.
What is an amorphous solid?
