Step 1:Let's solve this step by step:
Step 2:: Understand the concept of heat capacity
Heat capacity is a physical property that describes how much thermal energy a substance can absorb or release when its temperature changes.
Step 3:: Analyze the given options
Let's carefully examine each option: A. This describes temperature, not heat capacity B. This describes temperature resistance, not heat capacity C. This is close to the definition of heat capacity, but not precise D. This describes specific heat capacity, which is a more precise definition
Step 4:: Define heat capacity
Heat capacity is the amount of heat energy required to raise the temperature of a substance by one degree.
Step 5:: Distinguish between heat capacity and specific heat capacity
- Heat capacity refers to the total heat required for a specific sample - Specific heat capacity refers to the heat required per unit mass (typically per gram or kilogram)
Step 6:: Identify the correct answer
Option C is the closest to the definition of heat capacity, but Option D provides the most precise definition of specific heat capacity.
Final Answer
The quantity of heat that is required to raise 1 g of the sample by 1°C (or Kelvin) at a given pressure. Key Insight: Specific heat capacity (c) is mathematically expressed as: c = \frac{Q}{m \Delta T} Where: - Q is heat energy added - m is mass of the substance - \Delta T is temperature change
