Heat dissipation formula class 10
WebHeat energy = cmu, where m is the body mass, u is the temperature, c is the specific heat, units [c] = L2T−2U−1 (basic units are M mass, L length, T time, U temperature). c is the energy required to raise a unit mass of the substance 1 unit in temperature. 2. Fourier’s law of heat transfer: rate of heat transfer proportional to negative WebFormula Every substance has its own capacity to conduct heat. The thermal conductivity of a material is described by the following formula: K = (QL)/ (AΔT) Where, K is the thermal conductivity in W/m.K Q is the amount of heat transferred through the material in Joules/second or Watts L is the distance between the two isothermal planes
