How to Calculate Specific Heat of the metal?

How to calculate heat energy if we are unknown of specific heat?

• I was going through the formula Specific heat= (Heat Energy)/(mass*Change in temperature) so i was unknown of the formula for heat energy and i asked a question on Yahoo and almost I ...show more

  Hello Parth : The heat transferred from the Surroundings to the System when there is no thermodynamic work is given by : ------------------------------ For Non-Flow Process : ---------------------------------------... Q = Delta U + WB Since have no work: --------> WB = 0.0 Q = Delta U Delta U = change of the System's Internal Energy Q = ( m ) ( Cv ) ( T2 - T1 ) for sensible heating or cooling Cv = constant volume specific heat Q = ( m ) ( delta u latent ) for phase change like melting or vaporization delta u latent = latent internal energy of fusion or of vaporization For Steady Flow Process : ---------------------------------------... Q = Delta H + Delta KE + Delta PE + WSF Let Delta KE , Delta PE, and WSF be negligible [ ~ 0.0 ] Q = Delta H Q = ( m ) ( Cp ) ( T2 - T1 ) ..... for sensible heating or cooling Cp = constant pressure specific heat Cp ~ Cv for liquids and solids Cp = Cv + R for ideal gas Q = ( m ) ( delta h latent ) delta h latent = latent enthalpy of fusion or of vaporization for melting or vaporization A substance contains internal energy or enthalpy; not " heat energy ". Thermodynamic heat , Q , is heat transferred from the Surroundings to the System as the result of heat transfer.
