Chemistry - Ideal Gas Question with Solution | TestHub

In a P–V graph, a higher curve represents a higher temperature, and pressure increases $⟹$ (1,4).

In a V–T graph, volume increases linearly with temperature and can indicate constant pressure/volume changes $⟹$ (1,3,4).

In a P–T graph at constant volume $⟹$ a straight line $⟹$ a constant temperature relation $⟹$ (2).

A P–T graph also shows that pressure increases with temperature $⟹$ (1,3,4).
