cold-blooded tarantula(cold-blooded or exothermic) on a warm-blooded human hand(Endothermic).
With ∆H, a scientist can determine whether a reaction gives off heat(or"is exothermic")
or takes in heat(or"is Endothermic").
However, unlike typical Endothermic creatures such as mammals and birds,
tuna do not maintain temperature within a relatively narrow range.
The heavy elements could most plausibly have been produced by Endothermic nuclear reactions during a supernova, or by transmutation through
neutron absorption within a massive second-generation star.
The new standard of Endothermic system for industrial heat solutions with very high energetic efficiency,
for application and production cycles, such as for the drying of paint products and leather.
When encounter fire, the paint could rapidly expand and form a compact&uniform carbonized protective layer,
and generate decompose&Endothermic reaction to prevent heat transfer and extend the refractory time of steel structure.
If you mix barium hydroxide octahydrate and dry ammonium chloride in a beaker and place it on a wood block with water on it,
you can observe the chemical change because the reaction is so Endothermic, it freezes the water on the block.
