: [[Freezing]], [[Condensing]] and [[Depositing]] are [[exothermic]] changes because they release [[energy]] when they happen. The [[material]] has less [[energy]] after they have happened. However, there is usually no increase in [[temperature]] because the [[material]] is usually cooled to [[State Change|change state]]because the surroundings are colder than the [[material]] during this process.
