Instructions on how to use the Heat Absorbed or Released Calculator

  1. If the substance is in solid state only, write Tf instead of TM and write 0 instead of Lf, cl, LV and cg
  2. If the substance is in liquid state only, write Tf instead of TB, Ti instead of TM and write 0 instead of cs, Lf, LV and cg
  3. If the substance is in gaseous state only, write Ti instead of TB, and write 0 instead of cs, Lf, cl and LV
  4. If the substance passes through two, three or four stages, write 0 instead of the specific heat of the phase in which the substance doesn't get through
  5. If the substance cools down, switch the values of Ti and Tf to obtain the heat released by the object
