Gradient

A difference in specific physical or chemical values between two areas is called a what?

a gradient

The steeper the roof, the_ the _ ,and the _ the flow. Indeed unless they are inhibited from doing so.

Larger

Gradient

Greater

Substances always

Move down their gradient from high to low

What does the term resistance describe?

Resistance describes all factors that inhibit flow down a particular gradient

A smoother surface provides less_and permits a_amount of flow

Resistance

Greater

_Provide significant _ to flow

Barriers

resistance

The same principle applies in each and every case

Gradient promotes the flow of the substance, and the various factors of resistance opposed the flow
