What is SI unit of viscosity coefficient \(\mathrm{(\eta)}\) ?
1 Pascal
2 \(\mathrm{\mathrm{Nsm}^{-2}}\)
3 \(\mathrm{\mathrm{km}^{-2} \mathrm{~s}}\)
4 \(\mathrm{\mathrm{Nm}^{-2}}\)
Explanation:
SI unit of viscosity coefficient is 1 newton second per square metre \(\left( {{\rm{Ns}}{{\rm{m}}^{{\rm{ - 2}}}}} \right){\rm{ = }}\) pascal second \(\left( {{\rm{Pas = 1\;kg\;}}{{\rm{m}}^{{\rm{ - 1}}}}{\rm{\;}}{{\rm{s}}^{{\rm{ - 1}}}}} \right)\). In cgs system, the unit of coefficient of viscosity is poise

Increase in kinetic energy can overcome intermolecular forces of attraction. How will the viscosity of liquid be affected by the increase in temperature?
1 Increase
2 No effect
3 Decrease
4 No regular pattern will be followed
Explanation:
Intermolecular force of liquid decreases with increase in temperature, hence viscosity of liquid also decreases. However, some exceptions are there like liquid proteins and liquid sulphur.
