Metal #1 has a high heat capacity. Metal #2 has a low heat capacity.

If both metals are at 20 degrees C, their molecules have the same amount of kinetic energy, right?

No. Metal 1 molecules have higher kinetic energy. Heat capacity = energy required to raise something by 1deg. You can also think of it as how much energy the metal can store without changing temperature.

Can one only say that the average kinetic energy of the molecules will be same between two substances at equal temperatures if the substances are gases?

Thank you, MedPr. You're input is invaluable-'cause it's down to the wire---like 2 weeks lefts. Hopefully we'll soon see each other in the "2012/2013 Application Thread" :)

real gas would be similar to above solid heat capacity stuff i think.

for ideal

True for ideal gases, or between monoatomic/monoatomic and diatomic/diatomic gases (X and Y2). Anything more complicated and you're better off not making such an assumption.

Hopefully the 2012/2013 Matriculant thread (and the 30+ MCAT thread).
