CHXI06:STATES OF MATTER

Which of the following behaviour is true regarding the coefficient of viscosity \(\mathrm{(\eta)}\) of a liquid?
1 Plot of \(\mathrm{\eta}\) versus T is non linear
2 Plot of \(\mathrm{\eta}\) versus \(\mathrm{\dfrac{1}{T}}\) is linear
3 \(\mathrm{\eta=\dfrac{E}{R T}}\)
4 Plot of \(\mathrm{\log \eta}\) versus \(\mathrm{\dfrac{1}{T}}\) is non linear
Explanation:
The velocity decreases with an increases in temperature. Most liquids suffer the exponential relationship between tempature and viscosity rather than linear form.

The reciprocal of viscosity can be termed as
1 Surface tension
2 Fluidity
3 Density
4 Elasticity
Explanation:
If viscosity refers to resistance, then its inverse is ease of flow, i.e., fluidity.
CHXI06:STATES OF MATTER

Which of the following statement is incorrect about viscosity?
1 Greater the viscosity, the more slowly the liquid flows.
2 Hydrogen bonding and van der Waal's forces are strong enough to cause high viscosity.
3 Viscosity of liquids increases as the temperature rises
4 Glass is an extremely viscous liquid
Explanation:
Viscosity of liquids decreases as the temperature rises because at high temperature, molecules have high K.E. and can overcome the intermolecular forces to slip past one another between the layers.
