Specific heat (s) ;- It is the amount of heat require per unit mass of substance per unit change in temp
s=dQ/dT
in SI syatem J/kg/C
in cgs system cal/gm/C
DQ=mSdT
Q=m∫sdT
if s is independent of temp then
Q=ms∫dT
Q=msΔT
Value of s depends upon nature of substance
for water    s= 1cal/gm/C or 4200 J/kg/C
for ice s= 0.5 cal/gm/C
for steam  s= 0.46 cal/gm/C

S= 1cal/gm/C or 4200 J/kg/C is for water
s= 0.5 cal/gm/C is for ice
s= 0.46 cal/gm/C is for steam
