Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
The question asks for the standard laboratory apparatus used to measure thermal properties, specifically the specific heat capacity ($C_p$) of a substance.
Step 2: Detailed Explanation:
• Calorimeter: This is an insulated container used to measure the amount of heat involved in a chemical or physical process. To find specific heat, a known mass of a sample at a specific temperature is placed in a calorimeter containing water, and the final equilibrium temperature is measured.
• Equation: The heat lost by the sample equals the heat gained by the water and the calorimeter: $m_s C_s \Delta T_s = (m_w C_w + C_{cal}) \Delta T_w$.
• Analysis of other options:
• Hygrometer: Measures humidity.
• Thermometer: Measures temperature but not heat capacity directly.
• Manometer: Measures pressure.
Step 3: Final Answer:
A calorimeter is the primary instrument for calorimetry experiments. Option (C) is correct.
