Which of the following is a unique property of water?
Summary. Water molecules are polar, so they form hydrogen bonds. This gives water unique properties, such as a relatively high boiling point, high specific heat, cohesion, adhesion and density.
How does surface tension apply to the real world?
The effects of surface tension are of central importance in many everyday phenomena: it causes small droplets of rain to stick to your windows, creates bubbles when you add detergent in your sink, and propels water-striding insects on the surface of ponds.
Does surface tension depend on pressure?
Surface Tension of a liquid depends upon Atmospheric pressure, the nature of liquid and its temperature.
Why does viscosity increase with concentration?
The enhancement of the viscosity of the nanofluid at higher volume concentration is due to the higher shear rate. In contrast, the surface tension of the graphene–water nanofluid decreases with an increase in both volume concentration and temperature.
What happens when viscosity increases?
Viscosity is a measure of an oil’s resistance to flow. It decreases (thins) with increasing temperature and increases (or thickens) with decreased temperature. A general increase in viscosity at higher temperatures, which results in lower oil consumption and less wear.
What are the factors affecting the viscosity of liquids?
Factors Impacting Viscosity Fluid viscosity changes with temperature. Pressure has a small impact on gas viscosity and the pressure impact on the viscosity of a liquid is very small.
What are 3 factors that affect viscosity?
Terms in this set (7)
- Size. Smaller particle move/flow more easily than large particles.
- Shape. Bulky shaped particles affects the flow rate,the bulkier, the slower it flows.
- Speed. Slow moving particles are more viscous.
- Factors affecting viscousity.
