What is Specific Heat Capacity?
Specific heat capacity, often denoted as \( c \), is defined as the heat energy required to raise the temperature of a unit mass of a substance by one degree. The formula \( Q = m \cdot c \cdot \Delta T \) is derived from the first law of thermodynamics and is widely used in physics and engineering. Here, \( Q \) represents the heat energy (in Joules), \( m \) is the mass (in kilograms), \( c \) is the specific heat capacity (in J/kg·K), and \( \Delta T \) is the temperature change (in Kelvin or Celsius). This formula assumes no phase changes occur, ensuring its applicability to a wide range of scenarios.
