Viscosity is the measure of a fluid's resistance to flow, determined by the friction between its molecules as they move past each other. It is not specifically an inward force among molecules, but rather a property that affects how easily a liquid can flow.
Viscosity is not an inward force itself, but rather a measure of a liquid's resistance to flow, which arises from the internal friction between molecules. This friction is due to intermolecular forces, such as van der Waals forces and hydrogen bonding, that act between the molecules. As these forces resist the movement of the molecules past one another, they contribute to the overall viscosity of the liquid. Thus, while viscosity reflects the effects of these intermolecular forces, it is not an inward force like cohesion or adhesion.
The inward force among the molecules of a liquid is Surface Tension
When a liquid is heated, its temperature increases, leading to increased kinetic energy among its molecules. This causes the molecules to move more rapidly and can eventually result in a change of state, such as evaporation, where the liquid transforms into vapor. If heated sufficiently, the liquid may reach its boiling point, where it transitions to a gas throughout the liquid. Additionally, heating can also affect the liquid's viscosity and density.
The inward force among the molecules of a liquid is known as cohesive force. It is responsible for keeping the molecules together and creating surface tension in the liquid.
it flows easily

Water is the liquid that has the lowest viscosity and helium is the gas that has the lowest viscosity.
The molecules attract one another, via electric forces.
When a liquid hits a solid, several interactions occur, including adhesion and cohesion. The liquid molecules may stick to the solid surface due to adhesive forces, while cohesive forces among the liquid molecules can create surface tension. Depending on the speed of impact and the properties of both the liquid and solid, the liquid may spread, splash, or form droplets. The outcome is influenced by factors such as the viscosity of the liquid, the texture of the solid, and the angle of impact.
From wikipedia:"The cohesive forces among liquid molecules are responsible for the phenomenon of surface tension. In the bulk of the liquid, each molecule is pulled equally in every direction by neighboring liquid molecules, resulting in a net force of zero. The molecules at the surface do not have other molecules on all sides of them and therefore are pulled inwards. This creates some internal pressure and forces liquid surfaces to contract to the minimal area."
There are some gaps among molecules of liquid sulphuric acid where it may absorb the water molecules so it is a hygroscopic liquid.
