New page

==Key Stage 3==
===Meaning===
[[Internal Energy]] is the total [[energy]] of all the [[particle]]s in a [[material]].

===About Internal Energy===
: The [[particle]]s in a [[material]] have [[Kinetic Energy Store|kinetic energy]] because they move and several types of [[Potential Energy|potential energy]] because they are affected by [[force]]s. '''Internal Energy''' is all of those [[energy|energies]] added together.

===Examples===
: [[Water]] can exist as a [[liquid]] and a [[gas]] at 100[[°C]]. The [[Kinetic Energy Store|kinetic energy]] of the [[particle]]s in both is the same. However, the [[particle]]s in [[steam]] have more '''internal energy''' than the [[particle]]s in [[water]] because they are spread apart, giving them more [[Potential Energy|potential energy]].
: The [[particle]]s in [[petrol]] at 50[[°C]] are moving around so they have [[Kinetic Energy Store|kinetic energy]]. The [[petrol]] also has a store of [[Chemical Potential Energy|chemical potential energy]] that can be released when [[petrol]] burns in the presence of [[Oxygen]]. So the '''Internal Energy''' of [[petrol]] includes both the [[Kinetic Energy Store|kinetic energy]] of the [[particle]]s and the [[Chemical Potential Energy|chemical potential energy]].
