In general water, fresh water (0.01 S/m) to sea water (4 S/m), is more conductive than oil (more or less from 20 pS/cm to 1000 pS/cm)

What meaning of conductility?
It means, the ability to transfer heat, electricity or sound.Ok, now.Use a heat conductor as an example.A frying pan is a good heat conductor.Which means it has a high conductivity.This means a frying pan is good for heating as itabsorbs heat easily. That's why it is use for cooking.
What will happen if oil mixed with warm water?
Not a lot, water and oil don't mix and so the oil will float on top of the water.
Water oil glycerin how will they be layered?
Water on bottom, oil on top and glycerin between them.
What is use of insulator?
There are many types of insulators, for example heat insulators, water insulators (also called hydrophobic insulators) and current insulators. The role of an insulator is to avoid passage of something from a system to another. For example, a current insulator is placed in between two parts of an electrical systems in order to avoid they influence each other through current losses or an heat insulator is placed on the wall of an house to avoid that the internal heat is dissipated towards the external environment. To find good heat insulators is difficult. If we define the heat conductivity k like the heat transmitted for unitary temperature difference through a unit area and unit length of the insulation material, lower the conductivity better the insulation. The better insulators (silica aerogel) have an heat conductivity of about 0.001 in SI units (J m /°K). On the contrary very good electrical insulation can be attained, one of the better electrical insulators is Teflon, whose electrical conductivity (current per unit voltage on unit area and unit length) is as low as 10-23 A m/V. Regarding insulation from material infiltrations, (for example water insulators that are used to avoid humidity to penetrate inside a room) the conductivity is defined as transmitted quantity of water per unit concentration difference between the two sides of the insulator per unit area and unit length. Lower the conductivity higher teh insulation.
Does one cup of oil have the same mass as one cup of water?
Oil is less dense than water. Therefore, equal volumes of water and oil will not have the same mass. You can prove this by weighing each. The cup of oil will weigh less.
Why you use oil in transformer not water?
Oil or similar is used as a cooling fluid in electrical transformer, because it is electrically insulating - which water is not. The figure of merit is the lack of conductivity.
What is the electrical conductivity of ISO 150 gear oil?
stick an ohmmeter in it, that will measure the resistance. then you can tell us.
Does a ball float in water higher than in oil?
No, a ball will float higher in oil than in water because the density of oil is lower than that of water. The buoyant force experienced by the ball in oil is greater, causing it to float higher.
Why do you have to drain out water from the sepatory funnel and not vegetable oil when separating them?
- water has a higher density and is under oil- you need oil not water
Why is oil better to cook with than water?
Oil has a higher boiling point than water and so reaches a higher temperature than water which is important for most foods. In addition, oil has more flavour than water.

What is the thermal conductivity of crude oil?
Which crude?
What does the oil stay on the button when you mix oil and water?
This occurs because the oil has a higher density (mass divided by volume) that the water.
What does water not mix with?
Water and oil are immiscible. They do not mix, because they cannot form any chemical bonds together; The oil molecules have no electrical charge and are hydrophobic, or "afraid of water".
Which is hotter the boiling water or oil?
Boiling oil because it boils at a higher temperature
Why is sugar more soluble in water than in canola oil?
Water molecules have a higher electric polarity than oil.
Can vegetable oil boil more quickly than water?
No, because oil has a higher boiling point.
