q=msdT
dT = temperature change
m = mass
s = specific heat of water
differentiating it with t
we get power = msdT / t
dT = temperature change
m = mass
s = specific heat of water
differentiating it with t
we get power = msdT / t

Q= mcΔT,
where
Q is the symbol for heat transfer,
m is the mass of the substance,
and
ΔT is the change in temperature.
The symbol c stands for specific heatand depends on the material and phase.
The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00ºC.
The specific heat c is a property of the substance; its SI unit is J/(kg ⋅ K) or J/(kg ⋅ ºC).
Recall
that the temperature change (ΔT) is the same in units of kelvin and degrees Celsius.
If heat transfer is measured in kilocalories, then the unit of specific heat is kcal/(kg ⋅ ºC).
