Why is it easier to start a fire with kindling rather than with large sticks and logs of the same kind of wood?

Explained

Explanation:

Kindling can lead to higher temperature in shorter time than Large sticks or logs. In Kindling the surface area per unit mass is greater hence, heat transfer is quicker so, in less time it reaches its ignition temperature

Whereas in a log of wood heat is not as concentrated as in kindling as it conducts to a greater mass and hence , they are slower to reach the ignition temperature.

i'm thinking more like energy

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
