everything i know about thermodynamics

FIRST LAW Energy is conserved => Energy1 tranduced Energy2 E1=E2 SECOND LAW Energy= work + heat => w1 + q1= w2 + q2 AND Lord Kelvins statement "It is impossible to convert heat completely into work in a cyclic process" => That is, it is impossible to extract energy by heat from a high-temperature energy source and then convert all of the energy into work. At least some of the energy must be passed on to heat a low-temperature energy sink. Hence in our above example, w1 q2>q1 THIRD LAW Transduction is always happening (Transduce-To convert (energy) from one form to another) b/c absolute zero is not possible.
