Question

what is meant by specific heat capacity? How will
you Prove experimentily that
different substance have different specific heat capacities ?​

Answer 1

Answer:

SPECIFIC HEAT CAPACITY▫️

the heat required to raise the temperature of the unit mass of a given substance by a given amount

Explanation:

EXPERIMENT▫️

Experiment to prove different substances have different specific heat capacities:

Follow the figure below.

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 1000C. Now, put them immediately on the thick slab of wax. Note the depth that each of the balls goes into the wax. The ball which absorbs more heat from the water will give more heat to wax. More wax will thus 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 to intermediate depth. This shows that for equal rise in temperature, the three balls have absorbed different amount of heat. This means that the property which determines the amount of heat absorbed by a ball is different for three balls. This property is called the specific heat capacity.
