It is the amount of heat needed to raise the temperature of 1 kg of a substance by 1
A
Molar heat capacity
B
Specific heat
C
Thermal conductivity
D
Heat of fusion
Explanation: 

Detailed explanation-1: -The specific heat is the amount of heat necessary to change the temperature of 1.00 kg of mass by 1.00 ºC. The specific heat c is a property of the substance; its SI unit is J/(kg ⋅ ⋅ K) or J/(kg ⋅ ⋅ °C °C ).

Detailed explanation-2: -Specific heat capacity is the amount of heat required to raise the temperature of 1 kg of a substance through 1 kelvin. 2. The SI unit of specific heat capacity is J kg−1K−1 and in CGS it is cal g−1 ∘C−1.

Detailed explanation-3: -The specific heat capacity of a material is the energy required to raise one kilogram (kg) of the material by one degree Celsius (°C). The specific heat capacity of water is 4, 200 joules per kilogram per degree Celsius (J/kg°C). This means that it takes 4, 200 J to raise the temperature of 1 kg of water by 1°C.

Detailed explanation-4: -The amount of heat required to raise the temperature of 1kg of a substance by 1^()C is called the latent heat of the substance.

Detailed explanation-5: -One kilocalorie (1 kcal or 1000 calories) is the amount of heat (energy) needed to raise the temperature of one kg of water by one degree Celsius (°C). The SI standard unit for energy is Joule (J).
