Problem #1: A L sample of nitrogen inside a rigid, metal container at &#;C is placed inside an oven whose temperature is &#;C. The pressure inside the container at &#;C was at atm. What is the pressure of the nitrogen after its temperature is increased to &#;C?
Solution:
P1 P2 ––– = ––– T1 T2
x ––– = ––– Solution technique: cross-multiply and divide.
x = atm (to three sig figs)
Note: you will see position ups (especially in gas laws) that simply omit all the units in the solution. If you do that on a homework problem or check, you may acquire a deduction. It's not laziness on the part of the person writing the solution, it's simply assuming the reader knows what the units are and how they cancel out to leave the last unit.
Many times, you (as the student) are not allowed that luxury.
Problem #2: Resolve the pressure transform when a continual v
Explanation
(a) Gay - Lussac Regulation of combining volumes states that when gases react, they do so in volumes which are in simple ratios to one another and to the volume of the product, if gaseous, provided that the temperature and pressure remain constant.
(b) 2H\(_2\) + O\(_2\) -> 2H\(_2\)O. According to the equation, 2 volume of H\(_2\) requires 1 volume of oxygen.
50cm\(^3\) of H\(_2\) requires 25cm\(^3\) of oxygen,
volume of oxygen available = 30cm\(^3\),
volume of unused oxygen 30 - 25 = 5cm\(^3\).

Gay Lussac’s Law of Combining Volumes
Gay Lussac’s Law of Combining Volumes states that when gases react, they do so in volumes which bear a simple ratio to one another, and to the volume of the product(s) formed if gaseous, provided the temperature and pressure remain constant.
The law explains experimental facts about how gaseous atoms combine. Example:
For the reactions:
(i) N2(g) + 3H2(g) → 2NH3(g)
1 vol. 3 vols. 2 vols.
1 volume of nitrogen combines with 3 volumes of hydrogen to form 2 volumes of ammonia.
(ii) 2H2(g) + O2(g) → 2H2O(g)
2 vols. 1 vol. 2 vols.
2 volumes of hydrogen combine with 1 volume of oxygen to create 2 volumes of steam.
(iii) Cl2(g) + H2(g) → 2HCl(g)
1 vol. 1 vol. 2 vols.
1 volume of chlorine gas combines with 1 volume of hydrogen to form 2 volumes of hydrochloric acid.
