Answer:
C. mass
Step-by-step explanation:
Specific heat is defined as the amount of heat energy required to elevate the temperature of a material by 1°C per unit mass.
It is a physical property of a material. The standard international unit of heat capacity is joule per kelvin per kilogram (J/K/Kg).
If a substance has a high specific heat then it simply means that it will take very long to get heated but once heated it will take very long time to cool down either.
Water has highest specific heat.
