What is meant by specific heat capacity?
How will you prove experimentally that
different substances have different specific
heat capacities?
Answers
Answer:
☆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.
☆Explanation☆
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.
Hope it helps.
Explanation:
Answer:
Heat Capacity= Mass of Substances×Specific Heat capacity.We can prove that the Specific Heat capacity of the of the substances are different from each other. Equal Masses of the different substances the different amount of the heat energy to raise there temperature by the same amount.
Explanation:
Take three balls of iron, copper and lead of equal mass and put them in boiling water for some time. Then, take them out of the water and measure their temperature. All of them will be at temperature hundred degree celsius. Now, put them immediately on the thick slab of wax. Note the depth that each of the ball goes into the wax. The ball which absorbs more heat from the water will give more heat to wax. More wax will melt and the ball will go deeper in the wax. It will be observed that the iron ball goes deepest into the wax. Lead ball goes the least and copper ball goes the intermediate depth. This shows that for equal rise in temperature, the three balls have absorbed different amounts of heat. This means that the property which determines the amount of heat absorbed by a ball is different for the three balls. This property is called the specific heat capacity.
