Hot oil room temperature oil room temperature water below room temperature oil Which is likely to have the lowest viscosity?
Room temperature water is likely to have the lowest viscosity among the options provided. Water has a lower viscosity compared to oil, especially when the temperature is below room temperature. Oil typically has a higher viscosity compared to water.
Does water or motor oil flow faster?
Water is faster by it's lower viscosity, though oil viscosity is more temperature dependent than that of water.
How does temperature affect viscosity of motor oil?
Yes. If the temperature changes enough, the viscosity of oil will change, too. Oil is designed to resist changes in viscosity with temperature changes, at least to a degree. But if the change (either hotter or colder) is extreme, then the viscocity will most certainly change. And, as you'd expect, as it gets hotter, the viscosity of oil decreases (it get thinner), and as it gets colder, the viscosity of oil increases (it gets thicker).
What is the least viscous liquid known to man?
Liquid helium is the least viscous liquid known to man, with a viscosity that is even lower than that of water at room temperature. It exhibits superfluidity at temperatures close to absolute zero, where it flows without any viscosity.
Why As the temperature of oil sample decreases?
As the temperature of an oil sample decreases, its viscosity typically increases, meaning the oil becomes thicker and flows less easily. This change in viscosity can affect the oil's performance in applications such as lubrication or fuel. Additionally, lower temperatures can lead to increased wax formation in certain oils, which may further impact their behavior and usability. Overall, the physical and chemical properties of the oil can significantly change with temperature variations.

What refers to the tendency of oil to resist flowing?
Oil viscosity depends on it's temperature. The higher the oil temperature is, leads to higher viscosity and low flow resistance. Cold oil temperature leads to lower viscosity and higher flow resistance

Who has the lowest viscocity 10w30 or 20w40?
10W 30. The lower the number, the lower the viscosity or 'thickness'. Lower number means thinner oil at the same temperature
What is the viscosity of sunflower oil at 15 degrees Celsius?
The viscosity of sunflower oil at 15 degrees Celsius is approximately 60-70 centipoise (cP). Viscosity can vary slightly depending on the specific composition and brand of the oil. Generally, as temperature decreases, the viscosity of oils increases, making them thicker at lower temperatures.
What is light oil?
Light oil has a low density and flows freely when found in room temperature. It also has low specific gravity and low viscosity.
What is the least viscous liquid known to man?
Liquid helium is the least viscous liquid known to man, with a viscosity that is even lower than that of water at room temperature. It exhibits superfluidity at temperatures close to absolute zero, where it flows without any viscosity.
Why viscosity is important for engine oil?
Viscosity tells you the speed at which the oil will flow. The lower the viscosity the faster the oil will flow at 210 degrees fahrenheit as in an SAE30 weight oil. Any oil with a W attached such as SAE 10w30 means the oil was tested at a cold temperature and will flow as a 10 weight when it is cold and then performs as a 30 weight at 210 degrees.
What is the difference between 5w 30 and 10w 30 oil?
The numbers refer, mainly, to the viscosity of the oil and to the temperature range at which is should be used. The oil with the lower number would be less viscous and flow more easily in lower temperatures.
What is the difference between 520 oil and 530 oil?
When there are differences in numbers in motor oil, there is a difference in viscosity. A lower number has lower viscosity and is good for warmer climates. A higher number is good for colder climates.
How would you define viscosity - index?
Viscosity index is a measure of how an oil's viscosity changes with temperature. Higher viscosity index oils are more resistant to changes in viscosity with temperature, making them perform more consistently across a range of temperatures.
