Concept explainers
Interpretation:
The reason of using foam cup in a student calorimeter rather than a typical glass beaker is to be explained.
Concept introduction:
Calorimeter is an apparatus used to measure amount of heat involved in a
Answer to Problem 68A
Foam cup is used in student calorimeter because it is insulated. So no heat enters into the system or leaves the system.
Explanation of Solution
Calorimeter helps to measure amount of heat involved in a chemical reaction.
Foam cup is used instead of glass beaker because foam cup is insulated material. No exchange of heat takes place from it whereas from glass beaker there can be loss or gain of heat from surroundings which will alter the amount of heat change in the chemical reaction it self.
Student calorimeter consist of foam cup so that no exchange of heat takes place between system and surroundings.
