b. Convection occurs when temperature gradient exist in stationary fluid.

Explanation:

Convection : heat transport through fluid movement; It also occur when there is heat exchange between a solid and a fluid.

there are two types:

free convection: Only natural forces intervene (gravity). forced convection: designed by a man.

Q = h * A * ΔT

∴ h : film coeffcient
