Units for Internal Energy

Postby veneziaramirez 3I » Tue Feb 06, 2018 1:29 am

Does it matter which units to use for internal energy for our final answer. Is it kJ or J?

I believe that internal energy is usually represented in units of kJ.

I think you can use either in your answers, but try and maintain the one in which information was given in the question. Typically, one is also more favorable in terms of sig figs, but either should be fine

As long as you are consistent, I do not believe it matters whether you use kj or j.

It can be either one. Just depends on the problem.
