Shear stress (\( \sigma \)) and shear viscosity (\( \eta \)) are plotted as functions of the shear rate (\( \dot{\gamma} \)) for idealized "solid-like with yielding (1)" and "liquid-like (2)" materials.

Associate the shear stress and viscosity plots with the appropriate material responses.
At 215 °C, the viscosity of a polystyrene of molecular weight 250 × 103 g/mol is 8.0 × 103 Pa·s. The critical molecular weight of polystyrene, \( M_c = 35 \times 10^3 \) g/mol. For a similar polystyrene of molecular weight 500 × 103 g/mol, the viscosity (rounded off to nearest integer) will be \(\underline{\hspace{2cm}}\) × 103 Pa·s.
