I think the answer should be specific heat.

I don't know the correct meaning of thermal. Anybody explain it.

Thermal capacity also referred as heat capacity it is the amount of heat required to change the temperature of an object by a certain degree.

On the other hand, specific heat capacity also referred to as the specific heat of a material, is the amount of heat needed to raise the temperature of an object per unit mass of that object.

I have a little confusion now, please describe it clearly.

The heat capacity is the amount of heat required to raise the temperature of an object or substance one degree.

The thermal capacity is the amount of heat required to raise the temperature of an object or substance one kelvin.

Heat - 1 degree.

Thermal - 1 kelvin.

Thermal capacity of body substances 1 kg quantity of energy. So the answer is thermal capacity.

Specific heat of human body compared to substances like protein and wood.

Here the answer should be Specific Heat: Heat required to raise the temperature of a unit mass by given amount (usually one degree).

The thermal capacity of a body is defined as the amount of heat required to raise temperature of the body by 1 kelvin.

Mathematically, C=ms.
Where, m=mass of the body.
s=specific heat capacity.

Lets understand the Sp. heat: Amount of heat required to raise the body temp. by 1'C.

-->> lets take two different bodies & start heating assuming (initially both the bodies are at same temp, both the bodies needs different amount of energy to raise their temp. by 1'C ), that means the body whichever needs more energy to raise its temp by 1'C has more Sp. Heat.

Lets understand the thermal conductivity:

Lets take two bodies of same shape & size of two different materials and start heating at one end, after a minute observe the temperatures at another end, you feel both the bodies are having different temperatures,

It means the body which has more temp. has high thermal conductivity.

The relation between Sp. heat & Thermal conductivity is given by the term thermal diffusivity,

Observe carefully the terms in thermal diffusivity, & reduce one term by keeping another term constant, & observe the changes you will understand the difference between Sp. Heat & Thermal conductivity.
