With an increase in temperature, there is typically an increase in the molecular interchange as molecules move faster in higher temperatures. The gas viscosity will increase with temperature. With high temperatures, viscosity increases in gases and decreases in liquids, the drag force will do the same.
Q. Which gas has highest viscosity?
Of all fluids, gases have the lowest viscosities, and thick liquids have the highest….Noble gases.

Q. What is viscosity in liquids?
Viscosity, resistance of a fluid (liquid or gas) to a change in shape, or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow. The reciprocal of the viscosity is called the fluidity, a measure of the ease of flow.
Q. What is the main cause of viscosity?
When the inter-molecular forces of attraction are strong within a liquid, there is a viscosity. Cohesive forces are attractive forces exist between molecules of the same substance. So, cohesive forces are the main cause of viscosity.
Q. Is there a liquid with lower viscosity than water?
Everything I have come across that is low viscosity is inflammable – acetone, ether, silicone oil, fuel, etc. I have found some confusing things in my research. Acetone has a viscosity 3x less than water but weighs 2.5 times more.
Q. Is water less viscous than milk?
Water has a very low viscosity. Vegetable oil has a relatively low viscosity, as does milk. Viscosity is a concern when you need to know how quickly or how slowly a fluid flows. Viscosity can be very important, take engine oil for example.
Q. Is corn syrup more viscous than water?
Liquids that have a LOW viscosity flow quickly (ie. water, rubbing alcohol, and vegetable oil). Liquids that have a HIGH viscosity flow slowly (ie. Therefore, we’ve shown that corn syrup and honey have a higher viscosity (or are more viscous) than water and cooking oil.
Q. What is milk viscosity?
for natural pasteurized milk varied from 5.68 to 7.18 and for remade milk from 6.26 to 12.60 at 25°C. The viscosity of milk as determined is, to a certain extent, dependent upon the temperature at which the milk has been held. The viscosity is decreased slightly by pasteurization at 62−65°C.
Q. Which oil viscosity is best?
A lower number is better before the W for cold-weather performance, so a 5W oil is typically what’s recommended for winter use. However, synthetic oils can be formulated to flow even more easily when cold, so they are able to pass tests that meet the 0W rating.
Q. What happens if 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.
