Second Law of Thermodynamics

Two statements are equivalent

Reservoir

source of heat or a heat sink large enough that it does not
undergo a temperature change when heat is added or subtracted from it.

Add device to Clausius statement that doesn’t violate 2
nd

law with Q
L

= Q
L

it then reduces to a violation based on the Kelvin
-
Planck statement.
