Paraffin wax is an excellent material tostore heat, having aspecific heat capacityof 2.14-2.9 J g−1 K−1(joulepergramkelvin) and aheat of fusionof 200-220 J g−1.This property is exploited in modifieddrywallfor home building material: a certain type (with the rightmelting point) of wax is infused in the drywall during manufacture so that, when installed, it melts during the day, absorbing heat, and solidifies again at night, releasing the heatParaffin wax phase change cooling coupled with retractable radiators was used to cool the electronics of theLunar Rover.Wax expands considerably when it melts and this allows its use inwax thermostatic elementthermostatsfor industrial, domestic and, particularly, automobile purposes.
