Current Question (ID: 8221)

Question:

$\text{Increase in kinetic energy can overcome intermolecular forces of attraction. How will increase in temperature effect the viscosity of liquid-}$

Options:

1. $\text{Increase}$
2. $\text{No effect}$
3. $\text{Decrease}$
4. $\text{No regular pattern will be followed}$

Solution:

$\text{Hint: An increase in temperature decreases the resistance to flow}$ $\text{With the increase in temperature, the kinetic energy of the molecules of liquid increases which can overcome the intermolecular forces. Hence, the liquid starts flowing.}$ $\text{In other words, the viscosity of a liquid decreases with an increase in temperature. It has been found that the decrease is about 2\% per degree rise in temperature}$
