How much heat must be added to a system at 298 K for the number of accessible states to increase by a factor of 10^6 ?

Q=kTln(W)Q = kT ln(W)

where k is constant =1.38×1023= 1.38 \times 10^{-23 }

Heat

Q=(1.38×1023)×298×ln(106)Q=5.68×1020  JQ=0.3544  eVQ = (1.38 \times 10^{-23}) \times 298 \times ln (10^6) \\ Q = 5.68 \times 10^{-20} \; J \\ Q = 0.3544 \; eV
