GCSE P1 1.1.3 Energy Transfer by Heating
... In the marble, the thermal energy is transferred from particle to particle. Particles at the hot end vibrate more strongly and this increased vibration is slowly passed onto neighbouring particles along the length of the rod. Copper contains free electrons and these provide an additional thermal ene ...

Higher Frequencies Leading to Rising Power and EMI in
... The increasing speed of expensive processors is forcing less expensive "associated board" or “dependant” devices to keep up. Consequently, thermal management and EMI are becoming issues for traditional lower frequency or power devices, such as ASICS, memory, power resistors, controller chips, LEDs, ...

Thermodynamic functions - Phase Transformations Group
... The Helmholtz free energy F is the corresponding term at constant volume, when H is replaced by U in equation 9. A process can occur spontaneously if it leads to a reduction in the free energy. Quantities such as H, G and S are path independent and therefore are called functions of state. More About ...
