Question

What is meant by specific heat capacity? How will you prove experimentally substances have different specific heat capacities? ​

Answer 1

Answer:

specific heat capacity : quantity of heat needed to raise the temperature per unit mass.

Explanation:

Specific heat capacity is the quantity of heat needed to raise the temperature per unit mass for a substance.

How to prove experimentally that different substances have different specific heat capacities:  Take 3 balls of iron , copper and lead of equal mass and put them in boiling water for some time. Then take them out and measure their temperature all of them would be at 100°c. Put all of them on a wax layer and note down the depth all of them goes in to the wax. you can notice that iron ball goes the deepest and copper ball intermediate and lead ball the least . This shows that for the same rise in temperature 3 materials have absorbed different amount of heat.  which shows property that determines amount of heat absorbed by a ball is different for 3 balls. This property is specific heat capacity, hence specific heat capacity is different for different materials.
