Yes, The strength of the intermolecular forces in liquid is decreased in liquid as it is heated. The viscosity decrease with rising temperature due to low binding energy.
The strength of the intermolecular force decreases because the the H bonds are broken in water molecule on heating. The viscosity of the liquid decrease with rising temperature because, The molecules become more mobile as a result of the rise in temperature, which also causes the kinetic or thermal energy to rise. Because the attractive binding energy is lower, the viscosity is also lower. If you keep heating the liquid, the kinetic energy will eventually surpass the binding energy, allowing molecules to escape and possibly turning the liquid into a vapor.

The intermolecular forces remain the same in intensity, but when molecules heat up, their KE increases and they are better able to overcome them.
Cohesion between molecules is the primary factor contributing to viscosity in liquids. As the temperature rises, the cohesive force weakens because the energy of the particles increases, allowing for more fluid and free particle movement. As a result, we say that a liquid's viscosity reduces with temperature.
In gases, unpredictability and molecular collisions brought on by Crms (root mean square) velocity are a significant contributor to viscosity. Temperature increases cause molecules' kinetic energies to rise, which causes Crms to rise as well, increasing molecular collisions and unpredictability. The flow is challenging as a result. Thus, we say that the viscosity of gases rises with temperature.
