Specific Heat Capacity
The Amount of heat energy required by 1 kg of the substances to raise its temperature to 1 °C is called as Specific Heat Capacity.
Specific Heat capacity is denoted by the symbol 'c'. Its S.I. Unit is J/kgK.
●[Note ⇒ Specific Heat capacity should not be confused with the Heat capacity. Both are different from each other].
●Heat capacity is the amount of heat energy required by the body to raise its temperature by 1°C is called as Heat capacity.
●The Mathematical Relation between the Specific heat capacity and Heat capacity is ⇒
●Heat Capacity = Mass of the Substances × Specific Heat capacity.
We an prove that the Specific Heat capacity of the of the substances are different from each other.
Equal masses of the different substances required the different amount of the heat energy to raise there temperature by the same amount. For example, if equal masses of the Water and the copper are heated and there temperature are raised by 1 °C, then the amount of heat required by both the water and the copper is different, i.e., the heat energy requires by the water is nearly ten times that of copper. Thus, the amount of heat energy required by the Substances depends upon the nature or characteristics of the substances which is expressed in terms of its specific heat capacity.
Hence specific heat vary from substance to substance.

Answer:
Experiment to prove different substances have different specific heat capacities: Take three balls of iron, copper and lead of equal mass and put them in boiling water for some time. ... This shows that for equal rise in temperature, the three balls have absorbed different amounts of heat.
Explanation:
Specific Heat Capacity Experiment
The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1°C.
Steps to determine the specific heat capacity.
Place a beaker on a balance and press zero.
Now add the oil to the beaker and record the mass of the oil.
Read the starting temperature of the oil.
Connect a joulemeter to the immersion heater.
Time for thirty minutes.
Read the number of joules of energy that passed into the immersion heater.
Read the final temperature of the oil.
Use the following formula to calculate the specific heat capacity.
