How to know which compound is more stable if heat of formation values are given .Ans) Every compound tend to stay in lowest energy possible to be more stable, the less the energy it has the more its stable.During formation the more energy it gives out , lesser becomes its own energy, hence more is the stability of compound.
what is solid
Thermoplastic: These polymer gets soften on heating and can be converted into any shape that they can retain on cooling. Such polymers that soften on heating and stiffen on coolin
