The Ideal Gas Law
What is the temperature of 0.80 mol of a gas stored in a 275 mL cylinder at 175 kPa?
7.2 K
Which laws can be combined to form the ideal gas law?
Charles's law, Avogadro's law, and Boyle's law
Consider the proportionality below. What does this best represent?
Ideal gas law
Consider a balloon that has a volume V. It contains n moles of gas, it has an internal pressure of P, and its temperature is T. If the balloon is heated to a temperature of 15.5T while it is placed under a high pressure of 15.5P, how does the volume of the balloon change?
It stays the same.
Which proportionality applies to Avogadro's law?
V&N
Which equation agrees with the ideal gas law?
V1/T1=V2/T2
Avogadro's law and Charles's law describe a proportionality of the volume of a gas when the pressure is constant. Which describes the proportionality that allows these laws to be combined when describing a gas?
Volume is directly proportional to moles (Avogadro's law) and to temperature (Charles's law).
Which statement would be the most useful for deriving the ideal gas law?
Volume is directly proportional to the number of moles.
If the pressure, volume, and the number of moles of a gas are known, which is needed to calculate the universal gas constant from the ideal gas law?
the temperature of the gas
