A calorimeter is a device used for estimates the heat of chemical/ physical change.
The device is also capable of estimating heat capacity of a chemical.
Calorimeters are made of copper because copper is a good heat conductor, has a low specific heat capacity, and a light copper wall receives/delivers negligible heat.
A dissecting dish is a shallow container used primarily in biological and medical laboratories for dissection and examination of specimens.
The main use of Dissecting Dish is: The dish holds the specimen securely in place, often using a wax or silicone bottom where pins can be inserted to hold parts of the specimen.
Provides a convenient workspace for dissecting and examining various parts of the specimen with precision.
The shallow design of the dish allows for clear observation and manipulation of the specimen.
