1st law of Thermodynamics Worksheet
... In both A and B, the gas expands against the surroundings. Work is done on the surroundings (w < 0) because the external pressure suddenly decreases as the weight is removed from the piston and the gas expands to match the external pressure. 11. Is there a larger transfer of thermal energy as heat b ...

The Second Law of Thermodynamics
... The reciprocal of the absolute temperature is an integrating factor that permits the replacement of the inexact differential by the exact differential . The above equation is the Clausius definition of the entropy S. The first law of thermodynamics can be now expressed as for a reversible process ...

... never increase. (c) The internal energy of a system and its surroundings is never conserved during an irreversible process, but is conserved for reversible processes. (d) The work done by a closed system can exceed the decrease in the system’s internal energy Q2. An ideal monoatomic gas (Cv,m= 1.5R) ...
