Charles's Law describes the relationship between the volume and temperature of a gas at constant:
Pressure
Number of moles
Gas constant
All of the above
According to Charles's Law, when the temperature of a gas sample increases, what happens to its volume?
Volume decreases
Volume increases
Volume remains constant
Volume cannot be determined
Avogadro's Law states that equal volumes of gases, at the same temperature and pressure, contain equal:
Volumes
Numbers of moles
Densities
Masses
According to Avogadro's Law, when the number of moles of a gas increases, what happens to its volume?
Volume decreases
Volume increases
Volume remains constant
Volume cannot be determined
Which gas law directly combines Boyle's, Charles's, and Avogadro's laws into a single equation?
Ideal Gas Law
Dalton's Law
Graham's Law
Gay-Lussac's Law
The Ideal Gas Law equation is expressed as:
PV = nRT
V/T = k
P1V1 = P2V2
P1/T1 = P2/T2
In the Ideal Gas Law equation, what does 'R' represent?
Ideal gas constant
Temperature
Pressure
Volume
In the Ideal Gas Law equation, what does 'R' represent?
Ideal gas constant
Temperature
Pressure
Volume
Which gas law can be derived from the Ideal Gas Law by holding two variables constant?
Charles's Law
Boyle's Law
Avogadro's Law
All of the above
A sample of gas has an initial volume of 4.5 L at a pressure of 2.5 atm. If the pressure is increased to 4.0 atm while keeping the temperature constant, using Boyle’s law what will be the new volume of the gas?
