What does exothermic mean?

Answer 1

Jeremiah Adams

See Below.

What does the term "exothermic" mean?

The terms exo and themic denote giving and heat-related.

Exothermic, then, refers to something that releases heat.

I take it that we are working with chemistry here?

Exothermic change, then, is a change in which heat is liberated.

Change is what I meant to say, since it can be chemical or physical.

For Instance,

Physical Exothermic Change :- Dissolving #NaOH# in distilled

water. If you observe correctly, you will see that after #NaOH# is

When everything is completely dissolved, the solution will warm up.

#NaOH(s) rarr^(H_2O) = Na^+(aq) + OH^-(aq) + "Heat"#

Chemical Exothermic Change: A frequent illustration of this

is the process of combustion.

If you burn coal in the presence of Air, it forms #CO_2# with

release of heat, allowing the reaction to continue.

#C + O_2 = CO_2 + "Heat"# [Where #+ " Heat"# means heat is

freed.]

This is a great article that can tell you more about Exothermic Changes; I highly recommend reading it.

I hope this is useful.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
