Avogadros law
According to ________, the volume of a gas is directly proportional to its molar amount at a constant pressure and temperature.
metal crystal
When a(n) ________ receives a sharp blow, no spatially oriented bonds are broken; instead, the electron sea simply adjusts to the new distribution of cations.
Metallic solids
________, such as silver or iron, can be viewed as vast three- dimensional arrays of metal cations immersed in a sea of electrons that are free to move about.
Molecules
________ on the surface are less stable because they feel fewer attractive forces, so the liquid acts to minimize their number by minimizing surface area.
Charles's law
________: The volume of a gas is directly proportional to its kelvin temperature for a fixed amount of gas at a constant pressure.
Gay Lussac's law
________: The pressure of a gas is directly proportional to its Kelvin temperature for a fixed amount of gas at a constant volume.
Amorphous solid
________ is a solid whose particles do not have an orderly arrangement.
composition of air
The ________ does not change appreciably with altitude, but the total pressure decreases rapidly.
→Boyles law
The volume of a gas is inversely proportional to its pressure for a fixed amount of gas at a constant temperature
→Charless law
The volume of a gas is directly proportional to its kelvin temperature for a fixed amount of gas at a constant pressure
→Gay-Lussacs law
The pressure of a gas is directly proportional to its Kelvin temperature for a fixed amount of gas at a constant volume
Standard temperature and pressure (STP)
0 °C (273.15 K); 1 atm (760 mmHg)
Standard molar volume
Volume of one mole of any ideal gas at STP, 22.4 L> mol
Normal boiling point
The boiling point at a pressure of exactly 1 atm
Heat of fusion
The quantity of heat required to completely melt 1 g of a substance once it has reached its melting point
Heat of vaporization
The quantity of heat needed to completely vaporize 1 g of a liquid once it has reached its boiling point
surface tension
caused by the different forces experienced by molecules in the interior of a liquid and those on the surface
crystalline solids
solid whose atoms, molecules, or ions are rigidly held in an ordered arrangement.
covalent network solids
whose atoms are linked together by covalent bonds into a giant three-dimensional array
amorphous solids
solid whose particles do not have an orderly arrangement.
