Y do bubbles of air in water move faster than in oil?
Its actually quite simple, something we generally learn in school in such a way that we need understand the practical implication of it. Mostly, i did not understand the practical implications of the terms i learnt in school. I guess, i was just young then.
I should not move off the topic, ya it happens because water is less viscous than oil.
Yup viscosity the simple concept that i never really managed to understand in school. something that opposes any deformation in the shape due to stress.
In our case, as the bubbles move up they have to apply some force on the liquid they are in. This force is applied by bubbles is opposed by the force of the liquid to maintain inertia. It is still and it does not want to move on its own. See we are not responsible for being lazy, nature is. If the liquid has more inertia it will have a greater opposition towards the rising bubbles and the bubbles will move slowly and slowly.
hence bubbles in water move faster than those in oil, as water is less viscous as compared to oil.
