What is Specific Heat?
Definition and Importance
Specific heat, often denoted as c, is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius. This property is intrinsic to materials and varies widely between different substances. Understanding specific heat is essential for solving problems related to thermal energy, temperature changes, and heat capacity.
Units and Formula
The typical units for specific heat are joules per gram per degree Celsius (J/g°C). The fundamental formula associated with specific heat problems is:
Q = mcΔT
where Q is the heat energy transferred, m is the mass, c is the specific heat, and ΔT is the change in temperature.
Common Specific Heat Problems
