Viscosity is the resistance to flow (opposite of fluidity). Viscosity depends on primarily on the composition of the magma, and temperature . Higher SiO 2 (silica) content magmas have higher viscosity than lower SiO 2 content magmas (viscosity increases with increasing SiO 2 concentration in the magma).
What are the two major factors that affect viscosity Brainly?
Temperature, pressure (at very high value) and concentration are the factors on which viscosity of a fluid depends.
What are the three factors that affect the viscosity of the magma?
The three factors that influence the viscosity of a lava are temperature, the dissolved gases it contains, and its chemical composition .
What are the factors that affect viscosity?
The two main factors that affect viscosity are temperature and silica content .
Which magma has the highest viscosity?
The magma that has the highest viscosity is rhyolitic magma .
What are the primary factors affecting lavas viscosity?
The three factors that influence the viscosity of a lava are temperature, the dissolved gases it contains, and its chemical composition .
What is the relationship between viscosity and temperature?
The viscosity of liquids decreases rapidly with an increase in temperature , and the viscosity of gases increases with an increase in temperature. Thus, upon heating, liquids flow more easily, whereas gases flow more sluggishly.
What is viscosity What are the factors affecting viscous force in a liquid flowing in a tube?
Fluid flow in pipes is affected by many different factors: The viscosity, density, and velocity of the fluid . Changes in the fluid temperature will change the viscosity & density of the fluid. The length, inner diameter, and in the case of turbulent flow, the internal roughness of the pipe.
What are the 4 factors that affect viscosity?
- Temperature: The viscosity of liquids decreases by about 2% for each degree rise in temperature.
- Chemical Composition: ADVERTISEMENTS: ...
- Colloid Systems: The viscosity of lyophilic colloid solution is generally relatively high.
- Suspended Material:
What causes a viscosity increase of liquids?
Both cohesion and molecular interchange contribute to liquid viscosity. The impact of increasing the temperature of a liquid is to reduce the cohesive forces while simultaneously increasing the rate of molecular interchange. The former effect causes a decrease in the shear stress while the latter causes it to increase.
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 liquid has the highest viscosity?
One of the most viscous liquids known is pitch , also known as bitumen, asphalt, or tar. Demonstrating its flow and measuring its viscosity is the subject of the longest continuously running scientific experiment, begun in 1927 at the University of Queensland in Australia.
What increases the viscosity of magma?
Viscosity of Magmas
Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO 2 (silica) content magmas have higher viscosity than lower SiO 2 content magmas (viscosity increases with increasing SiO 2 concentration in the magma).
What is highly viscous?
A fluid that is highly viscous has a high resistance (like having more friction) and flows slower than a low-viscosity fluid. To think of viscosity in everyday terms, the easier a fluid moves, the lower the viscosity. ... Honey would move slower than water, so honey would have a greater viscosity.
How does gas content affect viscosity?
Higher silica content means higher viscosity . But lower temperatures and low gas content mean higher viscosity. Hence, lower viscosity and low gas content mean higher temperature of magma.
What are the factors affecting climate?
- Elevation or Altitude effect climate. Normally, climatic conditions become colder as altitude increases. ...
- Prevailing global wind patterns. ...
- Topography. ...
- Effects of Geography. ...
- Surface of the Earth. ...
- Climate change over time.
