  • With increase in temperature the viscosity of a) gases decreases

With the increase in temperature, the viscosity of

a) gases decrease

b) liquids increases

c) gases increase

d) liquids decreases

Answers (1)

The answer is the option (c) and (d)

If n is the coefficient of viscosity of a liquid, n\propto \frac{1}{\sqrt{T}}

In the case of the viscosity of gases, n\propto \sqrt{T}

As the temperature increases, kinetic energy in the gas molecules also increases and hence due to the collisions between the molecules, the viscosity increases.

Whereas in the case of a liquid, the kinetic energy increases with temperature, but the relative speed of the layers of liquid remains fairly the same as before. Hence option c and d are correct.
