Avogadro - Study guides, Class notes & Summaries

Absolute Zero - correct answer-The theoretical temperature at which the molecules of a substance have the lowest energy and hence the substance has minimum internal energy and no kinetic energy acoustic impedance - correct answer-product of density of medium and speed of sound in medium Activity - correct answer-The number of atoms of a radioactive substance that decay per unit time. amplitude modulation - correct answer-amplitude of carrier wave varies in synchrony with the displacement...

Boyle's Law P1V1=P2V2 Only applicable when the reaction is isothermal & maintains constant composition Charles' Law V1/T1=V2/T2 Only applicable when the reaction is isothermal & maintains constant composition Gay-Lussac's Law P1/T1=P2/T2 only applicable when the reaction is isochoric & maintains constant composition Combined Gas Law P1V1/T1=P2V2/T2 Avogadro's Law V1/n1=V2/n2 Only applicable when the reaction is isothermal, isobaric, & maintains constant compos...

Absolute Temperature A temperature value relative to absolute zero. Absolute Zero The lowest possible temperature of a system, where no heat remains and the particles in the system have no kinetic energy. Avogadro Constant The number of particles that make up one mole of any gas. Boltzmann Constant A constant relating the average kinetic energy of the particles in a gas, to the gas’ temperature. Boyle’s Law The pressure of an ideal gas is inversely proportional to its volume when ...
