Why water flows faster than vegetable oil ?

Is there any relationship between the easiness of water flow and the intermolecular forces in water compared to those in vegetable oil ?Why water flows faster than vegetable oil ?
I think the main reason why water is less viscous than vegetable oil is because water has a lower molecular weight than vegetable oil.





The intermolecular forces between water molecules are stronger than the intermolecular forces between oil molecules which should cause water to be more viscous than oil. However, since water molecules are a lot smaller, it turns out that water is less viscous despite the intermolecular forces.Why water flows faster than vegetable oil ?
water is thinner
Yes, the intermolecular forces between oil molecules are greater than water and make the liquid more viscous. The oil resists flow more than water.
Water has a lower viscocity.
because oil has a higher consitancy...is thicker...so the atoms are not as loose as in water-%26gt; flows slower
