The volume-temperature graphs of a given mass of an ideal gas at constant pressures are shown below. What is the correct order of pressures?
Options
- A{\text{p}_{1} > {\text{p}_{3} > {\text{p}_{2}
- B{\text{p}_{1} > {\text{p}_{2} > {\text{p}_{3}
- C{\text{p}_{2} > {\text{p}_{3} > {\text{p}_{1}
- D{\text{p}_{2} > {\text{p}_{1} > {\text{p}_{3}
Correct answer
B. {\text{p}_{1} > {\text{p}_{2} > {\text{p}_{3}
Step-by-step solution
Drawing a constant temperature line parallel to 'Y' axis, the isobar at higher volumes will be at lower pressure as at constant temperature.
