Physical adsorption or physisorption decreases with increase of temperature. 

According to Freundlich absorption isotherm:

$\frac{\mathrm{x}}{\mathrm{m}}=\mathrm{k}·{\mathrm{p}}^{1/\mathrm{n}} \left(\mathrm{n}>1\right)$

Observing the graph, we get the order of the temperatures as: ${\mathrm{T}}_2<{\mathrm{T}}_3<{\mathrm{T}}_1$
