In the kinetic molecular theory a gas behavior, particles of a gas tend to move____and collisions between tem are-____.

rapidly elastic

The boiling point of water at sea level is 100C At higher altitudes, the boiling point of water will be

lower, because the atmospheric pressure is lower.

Which of the following correctly describes the process of inspiration (air entering the lung)?

The lungs expand, causing their internal pressure to decrease

Complete the following statement: In Charles's Law, the volume of a gas____when the ____decreases


According to the kinetic theory of gases, a gas can be compressed much more than a liquid or solid because

the particles of a gas are very far apart.

In Gay-Lussac's Law, the pressure of a gas increases due to an increase in temperature because

the molecules strike the walls of the container more often.

Gay_Lussac's Law

pressure of a gas is directly related to Kelvin temperature increase in T, increase the P of a gas, decrease T decrease P of gas

Boyle's law

pressure of gas is inversely related to the volume when temp(K) and amount (moles) of the gas do not change

Charles's Law

volume of a gas changes directly w/ a change in Kelvin temp when pressure and amount (mole) of the gas do not change.

combined law

gas laws relating pressure, volume, and temperature. P1V1/T1 = P2V2/T2

Avogadro's Law

volume of gas is directly related to the number of moles of gas when pressure and temp do not change

ideal law

numerical value that relates the quantities P, V, n, and T int the ideal gas law, PV=nRT

molar volume

volume of 22.4L occupied by 1mole of a gas at STP conditions of 0 C (273) and 1atm

vapor pressure

the pressure exerted by the particles of vapor above a liquid

Avogadro's Law

Volume and Moles V1/n1=V2/n2

Dalton's Law

partial pressure a mixture of two or more gases, the total pressure is the sum of the partial pressures of the individual gases: P total=P1+P2+P3+........

properties of gas

pressure, volume, temperature and amount
