called-
-
A.
Specific Heat
-
B.
Thermal expansion
-
C.
Temperature stress
-
D.
Heat of hydration
Correct Answer:
A. Specific Heat
Explanation:
Specific heat is defined as the amount of thermal energy required to increase the temperature of a one-unit mass of a particular substance by one degree Celsius. This property is an intrinsic characteristic of a material, meaning it remains constant regardless of the substance's shape or size. Mathematically, it is expressed through the formula Q = mcΔT, where specific heat (c) represents the relationship between the heat added (Q), the mass (m), and the resulting temperature change (ΔT). Unlike thermal expansion, which refers to physical size changes, or temperature stress, which refers to internal pressure from heating, specific heat specifically quantifies a material's capacity to absorb heat relative to its mass and temperature.
