Unlike in the case of the solid fuel, the liquid or gaseous fuel spread through convection and radiation. In most cases, the flame spread is spontaneous as the fuel occupies the confined surface faster than solid materials. In addition, liquids and gases have low densities compared to solids, therefore, burn faster.

A black body is a body or surface which is not reflective at all. In other words, a black body is a body with absorptivity of 1 and hence it absorbs the entire radiation without reflecting any (Howard, 2000). On the other hand, a grey body refers to a body that reflects some of the radiation and hence its absorptivity is less than 1.

For linear motion, when an object is moving in a straight line, its speed in a given direction is the velocity (Asada, Futamase & Hogan 2011). Velocity increased with time is acceleration. In a circular motion, speed in a circle is angular velocity and when the angular velocity is increased, centripetal acceleration increases.
