What is the relationship between heat and specific heat?

The heat capacity and the specific heat are related by C=cm or c=C/m. The mass m, specific heat c, change in temperature ΔT, and heat added (or subtracted) Q are related by the equation: Q=mcΔT. Values of specific heat are dependent on the properties and phase of a given substance.

Is a higher specific heat capacity better?

Specific heat is Jg−oK . So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it.

Why does specific heat capacity not depend on mass?

We need to know the amount of heat energy per unit mass to get the specific heat. Hence specific heat does not depend on the mass of the body. As material to material the required heat energy will differ to get a temperature rise of 10oC per unit mass, the specific heat capacity depends on the material of the body.

Is specific heat and specific heat capacity the same thing?

Heat capacity is the amount of heat needed to change the temperature of a substance by 1 degree Celsius , while specific heat is the heat needed to change the temperature of 1 gram of substance by 1 degree Celsius. Whereas heat capacity is dependent on the amount of substance, heat capacity is independent of it.

What is the difference between heat and specific heat?

The main difference between specific heat and heat capacity is that specific heat is the amount of energy needed to raise the temperature of a given sample by 1 K while heat capacity is the amount of energy needed to raise the temperature of 1 kg of substance by 1 K.

What are some examples of specific heat?

Some examples of the specific heat capacities of different substances are listed below: Aluminum 902 J/kg°C Copper 385 J/kg°C Gold 129 J/kg°C Iron 450 J/kg°C Lead 128 J/kg°C NaCl 864 J/kg°C Oxygen 918 J/kg°C Water 4181 J/kg°C Brick / block: 840 J/kg°C Concrete: 880 J/kg°C

What are the units of specific heat?

The unit of heat capacity is joule per kelvin , or kilogram metre squared per kelvin second squared in the International System of Units (SI). The dimensional form is L2MT−2Θ−1. Specific heat is the amount of heat needed to raise the temperature of one kilogram of mass by 1 kelvin.
