Question

When a bomb calorimeter is used to determine the heat of reaction, which property of the system under investigation is most likely to remain constant?

• A. Number of molecules
• B. Pressure
• C. Temperature
• D. Volume

Answer 1

The correct option is D Volume

in a bomb calorimeter when we are finding the heat of reaction,

in that reaction is taking place thus number of molecules will not remain same.

also pressure and temperature don't remain same.

but volume of the calorimeter remains same.
