IDEAL GAS GAS UNGGUL A hypothetical gas whose pressure-volume-temperature
behavior can be completely accounted for by the ideal gas
equation.

MELTING PELEBURAN A process from solid phase change to liquid phase.

MIXTURE CAMPURAN A system containing more than one substance.

NORMAL BOILING POINT TAKAT DIDIH The temperature at which the vapour pressure of liquid
NORMAL equals the atmosphere pressure that is 1 atm.

PARTIAL PRESSURE TEKANAN SEPARA Pressure of one component in a mixture of gases. Pi = XiP.

PHASE FASA A homogeneous part of the system in contact with other
parts of the system but separated from them by a well-
defined boundary.

PHASE FASA A homogeneous part of the system in contact with the
other parts of the system but separated from them by a
well-defined boundary.
PHASE DIAGRAM GAMBARAJAH FASA A diagram that summarizes the conditions at which a
substance exist as a solid, liquid or gas .

TRIPLE POINT TAKAT TIGAAN The point at which the vapour, liquid and solid states of a
substance are in equilibrium.
VAPOUR PRESSURE TEKANAN WAP The pressure exerted by vapour in equilibrium with its
liquid in a closed container.

VISCOSITY KELIKATAN A measure of a fluid’s resistance to flow.
