Specific Heat

-
In the absence of a phase change, the amount of heat required to change the temperature of a
substance is given by q = mc(Change of T)
o M is the mass of the substance
o c is the specific heat of the substance
o Change of T is the change in temperature in either degrees Celsius or Kelvins
The specific heat of a substance is the nergy required to raise the temperature of exactly 1 gram
of the substance by 1 degree Celsius
o Change of T = TempFinal – TempInitial
Specific heat is intensive: it does not depend on the amount of matter, depends on the amount
of material
Heat is extensive and does depend on the amount of matter rather than material
o c = q/m(Change of T)
Final Temperature equals
o m1c1t1 + m2c2t2 / (m1c1) + (m2c2)
