Endothermic describes a chemical reaction that is accompanied by the absorption of heat, or an organism that generates heat to maintain its temperature. (adjective)
The narwhal is a mammal which makes it, by definition, endothermic.
Vaporization is an endothermic change.
endothermic change
Jack measured the endothermic change as the reaction progressed
An endothermic change requires heat, and an exothermic change releases heat.
yes it is endothermic
endothermic change
endothermic change
Yes, a positive enthalpy change is indicative of an endothermic reaction.
It is an exothermic change
An endothermic change requires heat, and an exothermic change releases heat.
Endothermic reaction: In an endothermic reaction, the products are higher in energy than the reactants. Therefore, the change in enthalpy is positive, and heat is absorbed from the surroundings by the reaction therefore enthalpy change show positive sign in a endothermic reaction..
