What happen to poison in heat?

Answer 1

It depends upon its nature, usually normal heat does not change the nature of inorganic compounds but an organic compound (poison) may be decomposed on heating.

Answer 2

When poison is exposed to heat, it may break down or decompose into different compounds. This process can sometimes reduce the toxicity of the poison, but it can also potentially release harmful fumes or gases into the air. It is important to handle and dispose of poisonous substances carefully to avoid any risks to health.
