WebThe second expression adding the lost and gained heat is easier to use because you do not need to remember which one has a negative sign. Practice 1. How much heat does it take to increase the temperature of a 540.6-g sample of Fe from 20.0 °C to 84.3 °C? The specific heat of iron = 0.450 J/g °C. answer WebFeb 1, 2016 · As a general rule, gravitationally bound systems have negative heat capacities. This is because in equilibrium (and remember we can't do classical thermodynamics without equilibrium anyway), some form of the virial theorem will apply. If the system has only kinetic energy K and potential energy U, then the total energy is of course E = K + U ...
