The amount of heat needed to increase the temperature of a 1-kilogram substance by 1°C is known as the specific heat of the substance.
the formula for specific heat of a substance is given as
c = Q/(m ΔT)
where Q = Heat required to change the temperature by 1°C
m = mass of the substance
ΔT = change in temperature.
the units of specific heat is given as Joules/(kilogram °C)
Specific heat.
"Different substances gain heat energy at different rates. A 1-kilogram substance's specific heat is a measure of how much heat must be added to it in order for its temperature to increase by 1°C."
