===About Surface Area to Volume Ratio===
{| class="wikitable"
|colspan="3"| As the size of an [[object]] decreases the [[Surface Area|surface area]] becomes larger compared to the [[Volume (Space)|volume]] of the [[object]].
|}
The '''surface area to volume ratio''' explains why
*A mouse will freeze quicker in cold [[temperature]]s than a bear because the larger the [[Surface Area|surface area]] the quicker an [[object]] can [[emit]] [[Thermal Energy Store|thermal energy]] and the smaller the [[Volume (Space)|volume]] the less [[Thermal Energy Store|thermal energy]] in the [[object]].
: A mouse has a large [[Surface Area|surface area]] compared to its [[Volume (Space)|volume]] so it loses [[Thermal Energy Store|thermal energy]] quickly.
*[[Multicellular]] [[organism]]s need specialised [[tissue]]s with large [[Surface Area|surface areas]] to [[absorb (biology)|absorb]] [[nutrient]]s and [[Oxygen]] because the larger the [[Surface Area|surface area]] the quicker an [[object]] can [[absorb (Biology)|absorb]] [[chemical]]s and the larger the [[Volume (Space)|volume]] the more [[chemical]]s the [[object]] needs.
: A [[multicellular]] [[organism]] has a large [[Volume (Space)|volume]] compared to its [[Surface Area|surface area]] so it needs parts of its body to have a large [[Surface Area|surface area]] to [[Absorb (Biology)|absorb]] enough [[nutrient]]s and [[Oxygen]].
*[[Catalyst]]s work better when made into [[nanoparticles]] because their [[atom]]s interact with the [[chemical]]s to increase the rate of a [[Chemical Reaction|reaction]] so when a [[catalyst]] is made into [[nanoparticle]]s the number of [[atom]]s on the surface of the [[object]] is greater compared to the [[Volume (Space)|volume]] of [[catalyst]].
