The Ideal Gas Law Applications

A gas is isothermally expanded. Which plot best shows this type of expansion?

Assume that you have a cylinder with a moveable piston. What would happen to the gas volume inside the cylinder if you decrease the pressure to one quarter the original pressure while holding the temperature constant? a. V1= 4 V2 b. No change in volume c. V2= ¼ V1 d. V1= ¾ V2 e. V2= 4 V1

Consider the process of 2 H(g) → H2(g) where ΔH = −436 kJ/mol Determine if the sentence below is true or false. When this reaction occurs in a sealed container at constant temperature, the pressure in the container should decrease.

Which of the lines on the figure below is the best representation of the relationship between the volume of a gas and its pressure, other factors remaining constant?  

A piece of metal, initially at room temperature, is heated. Neither a chemical change nor a physical change takes place. During this process what remains constant? A. The densityB. The massC. The volumeD. All of these properties remain constant. 

At constant temperature if the volume of a gas sample is tripled the pressure will 1. be increased by a factor of 6. 2. be tripled. 3. be cut in half 4. be one third the original. 5. remain the same.

In the ideal gas law P V = n R T, P and V are1. related, but not important.2. independent of each other.3. inversely proportional. 4. lovers.5. never related mathematically.
