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.

Is the inward force among the molecules of a liquid?
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.
What is the inward force among the molecules of a liquid?
The inward force among the molecules of a liquid is called cohesion. It is responsible for the surface tension of liquids and helps maintain the shape of liquid droplets.
What substance has the lowest viscosity?
Helium gas has the lowest viscosity among substances at room temperature and pressure.
What is the nature of attractive force among molecules in liquid bromine?
The attractive force among molecules in liquid bromine is primarily due to London dispersion forces, which are weak intermolecular forces that result from temporary fluctuations in electron distribution within molecules. These forces are responsible for holding the molecules together in the liquid phase.
A decrease in vapor pressure will cause?
A decrease in vapor pressure will cause the liquid to evaporate more slowly, as there will be fewer molecules escaping from the surface into the gas phase. This can result in a slower rate of evaporation and a decrease in the amount of gas molecules above the liquid.
Is the inward force among the molecules of the liquid?
The inward force among the molecules of a liquid is Surface Tension

What can you infer about the amount of friction among the particles of a liquid that has a low viscosity?
it flows easily
What substance has the lowest viscosity?
Helium gas has the lowest viscosity among substances at room temperature and pressure.
Why H2SO4 is hygroscophic?
There are some gaps among molecules of liquid sulphuric acid where it may absorb the water molecules so it is a hygroscopic liquid.
Why does viscosity vary with respect to temperature?
Viscosity is affected by temperature because it determines the speed of molecular motion in a fluid. At higher temperatures, molecules move faster and the fluid becomes less viscous because there is less resistance to flow. Conversely, at lower temperatures, molecules move slower, causing the fluid to become more viscous as there is more resistance to flow.
What is the difference between viscosity and surface tension?
Viscosity is a measure of a fluid's resistance to flow, while surface tension is the force that acts to minimize the surface area of a liquid. Viscosity affects how easily a fluid can flow, while surface tension affects how a liquid behaves at its interface with another material.
What is the nature of attractive force among molecules in liquid bromine?
The attractive force among molecules in liquid bromine is primarily due to London dispersion forces, which are weak intermolecular forces that result from temporary fluctuations in electron distribution within molecules. These forces are responsible for holding the molecules together in the liquid phase.
When liquid water is heated do molecules collide more often?
Yes, as liquid water is heated, the kinetic energy of its molecules increases, causing them to move faster and collide more often. This increased movement and collisions among the water molecules lead to a rise in temperature.
