What is the relationship between viscosity and surface tension?
Surprisingly, we found that the solutions with a higher viscosity than water had either less or the same surface tension as water, and we suspect this is due to the unchanged intermolecular bonding of water molecules (hydrogen bonding) causing surface tension as viscosity increased.
How do viscosity and surface tension change as temperature increases?
As temperature increases, viscosity and surface tension decrease because the raise in temperature speeds up the molecules and the movement makes the liquid move faster so the viscosity decreases.
What is the relation between the temperature and surface tension?
The strength of surface tension depends on intermolecular forces. As temperature increases, molecules of liquid become more active and they move more rapidly; therefore, the intermolecular forces are more instable. Surface tension decreases with increasing temperature.
What is the effect on surface tension of temperature class 9?
In general, surface tension decreases when the temperature increases because cohesive forces decrease with an increase in molecular thermal activity. The influence of the surrounding environment is due to the adhesive action liquid molecules have at the interface.
What is the effect of pressure on surface tension?
A decrease in surface tension with increasing pressure is, however, due to more similar densities between these dissimilar constituents. Related to this, it is found that the slope of surface tension with temperature itself decreases at higher pressures.
Does viscosity depend on density?
There is no direct relation between viscosity and density. In general, for any fluids, when the temperature is increased, its density decreases, thus the fluid becomes less viscous. …
surface tension of water helps creatures(mostly of insecta class such as water striders) to walk on water. it also helps water to move up the xylem tissue of higher plants without breaking up.
