Isothermal vs. isochronic

Hello again,

Last question for a while kinda confused between these two. Let's say i have these two processes, the internal energy of a system is removed(isothermal) and decreases by 50J(both of them).

Now for isothermal Q=W which would tell me that work equals 50J, correct and isochronic would also have a heat exchange of 50J, right?

Can you help me?

ps. let's use these questions for a better example if i have confused you.

1) During an isothermal process, 5J of heat is removed from the ideal gas. what is the work done in the process. its 5J, right

2) In a isochronic process, the internal energy of a system decreases by 50J, ok. what's the heat exchange? 50J, right

What is "isochronic"?

Did you mean "isochoric" (constant-volume process)

LMAO!

Hiya! Tom,
Yes i mean isocoric. Sounds like a new type of chronic/mary jane cig huh.
Thanks!

Yes.

Right again.

And three's a charm.

Try the following website. It's really great.

In the bubble map, click on "Heat and Thermodynamics". In the new menu, you will see, among other things, "Isothermal" and "Constant Volume" (aka "Isochronic" LOL).
