how does the heat required to raise the temperature of water by a certain amount compare with the heat required to raise the same mass of iron by the same amount? take s.p. heat of water 4186Jkg^-1k^-1,and specific heat of iron 452Jkg^-1k^-1

ANSWER
If by supplying a heat of Q to a substance of mass m, its temperature increases by Δt, then
Q∝mΔt
or Q=cmΔt
where c= constant of proportionality , called specific heat capacity of the body.
Now, if m=1,Δt=1
o
C ,
then, Q=c
therefore, specific heat is the heat required to raise the temperature of unit mass of substance by one degree Celcius.
