Specific Heat
Key Questions

Specific heat represents the amount of heat required to change a unit mass of a substance by one degree Celsius. This is expressed mathematically as:
#q = m * c * DeltaT# , where#q#  the amount of heat supplied;
#m#  the mass of the substance;
#c#  the respective substance's specific heat;
#DeltaT#  the change in temperature.So, if we want to determine the units for specific heat, we'll just isolate the term in the above formula to get
#c = q/(m * DeltaT)# . Since heat is measured in Joules (J), mass in grams (g), and temperature in degree Celsius (#C# ), we can determine that#c = J/(g * ^@C)# .Therefore, specific heat is measured in Joules per g times degree Celsius.

Specific heat is an intensive property (like density, color, etc.) that does not depend on the amount of a substance present. This allows substances to be identified using their specific heat.
Imagine an unknown metal of known mass is heated to a known temperature. The heated metal can then be placed into a sample of water for which the volume (and therefore mass since 1mL=1g) and temperature are known.
The amount of energy (Q) transferred to the water can be calculated by using the equation
#Q_w=m_wC∆T_w# since the mass (m) and ∆T(temp change) can be measured.This allows for a calculation of the C value for the metal since the head gained (Qw) of the water will equal the heat lost by the metal (Qm).
The C value for the metal allows the metal to be identified.
