Q77 · Chemistry
Which amongst the following options is correct graphical representation of Boyle's Law?
The figure, described in words
All four options are graphs (P vs T, P vs V, P vs 1/V lines, P vs 1/V curves) with labelled isotherms/isochores.
- 1[graph: P vs T, straight lines through origin labelled V1, V2, V3 with V1 < V2 < V3 (V1 steepest)]
- 2[graph: P vs V, rectangular hyperbolas labelled T1 (outermost), T2, T3 (innermost) with T3 > T2 > T1]
- 3[graph: P vs 1/V, straight lines through origin labelled T3 (steepest), T2, T1 with T3 > T2 > T1]Official answer
- 4[graph: P vs 1/V, hyperbola-like curves labelled T3 (outermost), T2, T1 (innermost) with T3 > T2 > T1]
