Newton Leibniz 3 laws

1⃣  Power from universal gravitation   FⒶ =  GMm / r^2          = GmM / r^2        = F@      

2⃣ F = m Σ a

3⃣ In ALL action, energy is preserve.

heat physics 3 Laws

⓪ heat moves   within 2 things H & U              till    H & U become     same temperature       ... balance of heat

① δU = - δW + δQ       

   δ means change amount of something                                                                                                           ...

      U :  total         internal energy

      W : output      length ・　Force       from system

      Q : input         heat into system

② Clausius's fundamental

     if there is 2 things A & Q            

     if temperature of A = T(A)   and temperature of Q = T(Q)

     if T(A) < T(Q),              move only heat itself from A to Q is  impossible                  (without quantum physics)

③ Nernst fundamental

    temperature of A = T(A) => "absolute" 0 temperature is impossible                         (without quantum physics)

 

lets find path

within

1⃣2⃣3⃣   and   ⓪①②③

 

⓪ now we know heat is movement of molecule into 3 axis.    (heat energy = 1/2 mvx^2 + mvy^2 + mvz^2)       

                                                                                                                                   vx... speed element of x axis

  (i think SMALL waving of molecule which can't observe because Hisenberg's uncertainty might become mass ( e = mc^2 ))

    now,   H and U is confronting.

                                                                              T(H) < T(U)

     1/2 Σm(i)v(i)^2                 things H                                                                things U           1/2 Σm(i)v(i)^2

                                                                                     h|u

      lets zoom up    confronting 2 molecules .         1 molecule h of H   1 molecule u of U      

 

      if 2 things crush & Force moves to another thing,

      slower thing is pushed by faster thing.

 

◎   slow                           <=                     fast                            (can attack)                  h  1/2 mv^2  <= (energy)  u 1/2 mv^2

 ✕  slow                           =>                     fast                            (can't attack)                 h  1/2 mv^2  =>/ (energy)  u 1/2 mv^2

     between 2 molecules, always faster thing push slower thing.

     so heat moves from Low temperature to High temperature.

 

①   preservation of energy == infinity energy resource system is possible or not.

        (if not think another world) 

       if heat energy is shown with move of molecule,   we may think heat energy can thought as movement of molecules.

       we have to prove

                                                      heat energy = friction (comes from confliction)           = x F

                                                                                                                                          = 1/2 mv^2(before) - 1/2 mv^2(after)

       and to think change of mass,

                                                     e = mc^2

② ⓪ might be reason why.

 

③ if ② is true,           

     if all things have Temperature > "absolute" 0 temp, 

     its difficult to        temperature Tλ to be 0                       with          move heat of λ  into ξ

 

      p pressure

      v volume of gas

      T temperature

      n moll = amount of gas

      R ideal gas constant

     WE CAN DOWN TEMPERATURE WITH

      pv = TnR (Boyle = Charles's Law (of experience))

      pressure become softer, T become cooler.

      but if pressure of gas never become 0,

                    temperature never become 0
