Internal Energy and heat

Postby Ardo 2K » Sun Mar 11, 2018 9:55 pm

When the temperature of a system doesn't change does the heat equal 0? Or is that just the change in the internal energy of the system?

If a system is isothermal we can be positive there is no change in the system's internal energy because of the equation U=3/2nRT. This does not mean that the system could have no change in heat, because if the system is adiabatic as well there would be no change in heat.

well since q=m*c*delta T, if delta T=0, q must also equal 0.
