Characteristics PCMs latent heat storage can be achieved through solid–solid‚ solid–liquid‚ solid–gas and liquid–gas phase change. However‚ the only phase change used for PCMs is the solid–liquid change. Liquid-gas phase changes are not practical for use as thermal storage due to the large volumes or high pressures required to store the materials when in their gas phase. Liquid–gas transitions do have a higher heat of transformation than solid–liquid transitions. Solid–solid phase changes are typically very

By Newton’s law‚ -eE = mdvd/dt dvd = -eEdt/m Integrating‚ Vd = -eEt/m + Constant When t = 0‚ vd = 0 Therefore Constant = 0 Vd = -eEt/m --------------- (1) Electrical conductivity Consider a wire of length ‘dl’ and area of cross section ‘A’ subjected to an electric field E. If ‘n’ is the concentration of the electrons‚ the number of electrons flowing through the wire in dt seconds = nAvddt. The quantity of charge flowing

Velocity— Is speed in a given direction‚ and is also a vector. Acceleration— is the rate of change of velocity in a given direction (velocity/time). The unit in SI is metres per second
