Final answer:

Specific heat capacity is the amount of heat needed to change the temperature of a substance by 1°C. It varies among substances and plays a crucial role in scientific calculations.


Explanation:

Specific heat capacity (c) is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius. It is a crucial property in determining how substances respond to changes in temperature.

The specific heat capacity varies for different substances depending on their molecular structure and composition. For example, water has a high specific heat capacity, making it resistant to temperature changes.

Understanding specific heat capacity is vital in fields like thermodynamics, where precise heat calculations are necessary for various scientific applications.
