This also has practice with Boyle's Law, Charles' Law, and Gay-Lussac's Law, which can be derived from the combined gas law:
Combined Gas Law | At conditions of | Becomes | Also Known As |
\(\frac{P_1 V_1}{T_1}=\frac{P_2 V_2}{T_2}\) |
Constant Temperature (T1 = T2) |
\(P_1 V_1=P_2 V_2\) | Boyle's Law |
\(\frac{P_1 V_1}{T_1}=\frac{P_2 V_2}{T_2}\) |
Constant Pressure (P1 = P2) |
\(\frac{V_1}{T_1}=\frac{V_2}{T_2}\) | Charles' Law |
\(\frac{P_1 V_1}{T_1}=\frac{P_2 V_2}{T_2}\) |
Constant Volume (V1 = V2) |
\(\frac{P_1}{T_1}=\frac{P_2}{T_2}\) | Gay-Lussac's Law |
Exercise \(\PageIndex{1}\)
You have a sample of gas with a pressure of 1.86 atm, volume of 4.33 L, and temperature of 26.5 °C. If you cool it to 12.7 °C and decrease the volume to 3.45 L, what will the pressure be?.
- Answer
-
2.23 atm.
Exercise \(\PageIndex{1}\)
You have a flexible container of gas with a volume of 5.220 L at 19.4 °C. At what temperature would the volume increase to be 6.000 L?
- Answer
-
336.3 K or 63.1 °C.
