Question

Specific heat is the amount of heat required to raise the temperature of $ 1g $ of a substance by what?

Answer 1

Hint: The specific heat capacity or occasionally massic heat capacity of a substance is the heat capacity of a sample of the substance divided by the mass of the sample. The specific heat capacity of a substance, especially a gas, may be significantly higher when it is allowed to expand as it is heated (specific heat capacity at constant pressure) than when it is heated in a closed vessel that prevents expansion.

Complete Step By Step Answer:
The heat capacity is the amount of heat, expressed usually in Joules or calories, needed to change the system by $ 1 $ degree Celsius. The specific heat capacity is the amount of heat required to raise $ 1 $ gram of a substance by $ 1 $ degree Celsius.
In order to calculate the amount of heat necessary to raise something by a certain temperature change, we will need certain information.
Temperature Change.
Amount of Substance.
Usually given in grams or moles of substance.
Specific Heat Capacity or Heat Capacity
We can now use the following formula to solve for the amount of heat needed.
 $\Rightarrow q = m{C_p}\Delta T $
Where, $ q = $ quality of heat.
 $ m = $ Mass of substance.
 $ \Delta T = $ Change in temperature.
 $ {C_p} = $ specific or molar heat capacity.
 $ C = $ Heat capacity.

Note:
Remember that you don't always have to use the specific or molar heat capacities. One can use a normal heat capacity to find the energy, in which case the amount of substance isn't necessary information. This is when you would use the second equation.
