Question

The SI unit of specific heat is​

Answer 1

The specific heat capacity (symbol cp) of a material is the heat capacity of a sample divided by the mass of the sample in thermodynamics. Specific heat capacity is also known as massic heat capacity. Informally, it is the quantity of heat that must be added to one unit of mass of a substance to create a one-unit temperature increase. The joule per kelvin per kg, or  J⋅kg−1⋅K−1, is the SI unit for specific heat capacity. For example, it takes 4184 joules of heat to increase the temperature of 1 kg of water by 1 K, hence water's specific heat capacity is 4184 J⋅kg−1⋅K−1

Answer 2

Answer:

1. Specific heat capacity is defined as the amount of heat required to raise the temperature of 1 kilogram of a substance by 1 kelvin.

2. The SI unit of specific heat capacity is joule per kelvin per kilogram, J⋅kg−1⋅K−1.

3. For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules.

4. So the specific heat capacity of water is 4184 J⋅kg−1⋅K−1.
