Which of the following equations gives the combined relationship of Boyle's law and Charles's law?
Show Hint
Always use temperature in Kelvin while applying gas laws.
Updated On: May 19, 2026
- \( \frac{P_1V_2}{T_1} = \frac{P_2V_1}{T_2} \)
- \( n = \frac{RT}{PV} \)
- \( \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} \)
- \( P = \frac{RT}{nV} \)

The Correct Option is C
Solution and Explanation
Concept: Combined Gas Law:
\[
\frac{PV}{T} = \text{constant}
\]
Step 1: Writing the combined gas law.
\[ \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} \]
Step 2: Analyzing the options.
• Option (1): Incorrect equation
• Option (2): Incorrect ideal gas law form
• Option (3): Correct combined gas law
• Option (4): Incorrect ideal gas law form
