Answer:
C.
Explanation:
Specific heat capacity of a substance can be defined as the amount of heat a gram of the substance must lose or absorb in order to change its temperature by a degree Celsius. It is measured in Joules per kilogram per degree Celsius (J/kg°C).
Generally, the specific heat capacity of water is 4.182J/kg°C and is the highest among liquids.
Heat capacity or quantity of heat is given by the formula;
Where;
Q represents the heat capacity or quantity of heat.
m represents the mass of an object.
c represents the specific heat capacity of the substance.
dt represents the change in temperature.
Hence in calculating the relationship between the amount of heat added to a substance and the corresponding temperature change, the specific heat capacity is usually represented by the symbol C.
