otez555 [7]

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;

Q = mcdt

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.
