Choose the correct option for graphical representation of Boyle's law, which shows a graph of pressure vs. volume of a gas at different temperatures : 1. [graph option - see figure] 2. [graph option - see figure] 3. [graph option - see figure] 4. [graph option - see figure]

Doubtly AI · Accepted Answer

Answer: 4. [graph option - see figure] Key idea: Boyle's law: PV=constant at fixed T, so P vs V is a rectangular hyperbola. A higher T gives a larger constant, so the curve lies farther from the axes. Option 3 (straight lines) and option 2 (horizontal line) are not hyperbolas. Options 1 and 4 are hyperbolas, but in option 1 the 200 K curve is highest, which is wrong. In option 4, 600 K is the highest curve and 200 K the lowest, as PV=nRT requires.
