Thermo question

Test Preparation

<p>Is it that Q=nC(delta)T or U=nC(delta)T?
where Q is heat, C=molar specific heat, U=internal energy, n=# of moles, and (delta)T=change in temperature in K</p>

<p>I've seen some references say that the first equation is true and others say that the second one is true. however, they can't both be true</p>

<p>thanks</p>

<p>well at constant volume, heat change=internal energy change....so both the equations can be correct...</p>
