Step 1
What is the specific heat of a compound?
Answer
Specific heat is a fundamental concept in thermodynamics. It refers to the amount of heat energy required to raise the temperature of a unit mass of a substance by one degree Celsius (or one Kelvin).
In this context, when we analyze the provided options, the correct definition aligns with option (D): 'The quantity of heat required to increase the temperature of 1 g of the compound by 1 °C.'
This is a direct measurement that specifies both the mass and the temperature change, making it a precise definition of specific heat.
