Gases
The three physical properties of gas.
What are Fluidity, Compressible, and low density?
The basic building block that determines the overall form of a crystal.
What is unit cell(s)?
The stronger the intermolecular attractive forces are, and the mass is, the ____ the viscosity.
What is higher?
As dispersion forces become stronger, the size of the particles ____.
How do particles increase?
The phase changes that release energy.
What are freezing, condensation, and deposition?
When an object’s kinetic energy increases, the gas particles reacts by ___.
When do particles move faster?
When a substance exists in multiple states at the same time.
What is an allotrope?
The attraction of particles in the surface layer by the interior of a liquid.
What is surface tension?
The three intermolecular forces.
What are dispersion force, dipole-dipole, and hydrogen bonds?
The phase changes that require energy.
What are melting, evaporation, vaporization, boiling, and sublimation?
These two chemists proposed the kinetic-molecular theory
Who are Ludwig Boltzmann and James Maxwell?
A crystals ___ include cubic, tetragonal, orthorhombic, triclinic, hexagonal, rhombohedral, or monoclinic.
What is formation/structure?
The factors that influence the viscosity of a liquid.
What are intermolecular forces, size, and shape of the particle?
The attraction between the aligned opposite charges.
What are dipole-dipole forces?
The difference in the phase diagrams for water, carbon dioxide, and carbon.
What are normal boiling and freezing temperatures?
The motion of gas molecules.
What is extremely quickly and bouncing off each other?
Solids whose particles are not arranged in a regular or repeating pattern that also does not include crystals.
What are amorphous solids?
The force of attraction between identical molecules and between molecules that are different.
What is cohesion and adhesion?
The difference between intermolecular forces and intramolecular forces regarding bonding.
What is intermolecular forces are weaker?
The point on a phase diagram that represents the temperature and pressure at which three phases of a substance can coexist.
What is triple point?
The three additional units, besides pascal, that measure pressure.
What are Millimeter of mercury (mmHg), pounds per square inch (psi), and inches of mercury (inHg)?
The five categories of Crystalline solids.
What are atomic, molecular, covalent network, ionic, and metallic solids?
The lowering of water's surface tension by the deconstruction of hydrogen bonds.
What are surfactants/surface-active agents?
This force of attraction explains why, at normal temperature, water is a liquid while molecules of comparable masses are gases.
What are hydrogen bonds?
The difference between the exothermic process and the endothermic process.
What is the release of heat (exothermic) or the absorption of heat (endothermic)?
