The Ideal Gas Law
What is the pressure of 0.540 mol of an ideal gas at 35.5 L and 223 K?
28.2 kPa
What is the temperature of 0.80 mol of a gas stored in a 275 mL cylinder at 175 kPa?
7.2 K
Which law states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant?
Avogadro's law
Which laws can be combined to form the ideal gas law?
Charles's law, Avogadro's law, and Boyle's 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.
A student uses 0.0821 L• atm/mol • K as the value of the gas constant. What is most likely true about the variables in the ideal gas law?
V has the units of liters, and T has the units of kelvin.
Consider the proportionality below. What does this best represent?
ideal gas law
Which law relates temperature, pressure, volume, and the number of moles of a gas under perfect conditions?
ideal gas law
Which law relates to the ideal gas law?
not D.
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
