How will raise in temperature affects the viscosity of liquids and gases?

Options

ABoth increases
BBoth decreases
CIn case of liquids, decreases and in case of gases, increases.
DIn case of liquid, increases and in case of gases, decreases.

Correct answer

B. Both decreases

Step-by-step solution

In case of liquids, cohesive forces decrease and hence, their viscosity decreases while increasing the temperature. However, in case of gases, with the increase in temperature kinetic energy of gaseous molecules increases and the molecules become more mobile.
