Liquid specific heat capacity experiment

Experiment 10: Specific heat capacity of liquid

【Purpose requirement】

1. Use the cooling method to determine the specific heat capacity of the liquid, and understand the advantages and conditions of the comparison method;

2. Use the least square method to find the slope of the straight line in the empirical formula;

3. Use the experimental method to investigate the relationship between the cooling rate of the thermal system and the temperature difference between the system and the environment.

【Instrument description】

There are special calorimeters for the inner and outer cylinders, and they must meet the cooling conditions of the experimental system in a constant temperature environment.

【Experiment content】

1. Determine the specific heat capacity of saturated brine by cooling method;

2. Requirements for data processing;
