Read each question carefully and answer to the best of your ability. Show all your work for calculations. Use R = 0.0821 L·atm/(mol·K) or 8.314 J/(mol·K) as appropriate.
1. The Ideal Gas Law is represented by the equation .
2. In the Ideal Gas Law, 'P' stands for , 'V' for , 'n' for , 'R' for the , and 'T' for .
3. Temperature must always be expressed in when using the Ideal Gas Law.
1. Which of the following conditions are assumed for an ideal gas?
Particles have significant volume.
Particles attract each other.
Collisions are elastic.
Gases are easily liquefied.
2. What is the standard temperature and pressure (STP) for gases?
0°C and 1 atm
25°C and 1 atm
0 K and 1 kPa
273 K and 101.325 kPa
1. A container holds 0.50 mol of an ideal gas at 25°C and a pressure of 1.2 atm. What is the volume of the container?
2. If 10.0 L of hydrogen gas at 27°C and 740 mmHg contains 0.40 mol, what is the pressure if the temperature is increased to 100°C and the volume is reduced to 5.0 L?
3. Calculate the number of moles of a gas contained in a 3.0 L flask at 1.5 atm and 300 K.
1. The Ideal Gas Law is applicable under all conditions of temperature and pressure.
True
False
2. Real gases behave most like ideal gases at high temperatures and low pressures.
True
False
Explain why the Ideal Gas Law is a useful model despite the fact that no gas is truly 'ideal'.
