Question

HQ5.37 Which of the following explains why the bomb calorimeter exemplifies the First Law of Thermodynamics. A It requires the slow flow of heat energy and information is not lost B The loss of heat energy from the sample becomes the gain in heat energy of the water bath C It operates under standard isobaric conditions

Answer 1

This is essentially:

Heat lost by reaction = Heat gained by the calorimeter

there is conservation of energy, which relates to the 1st law; that all energies are conserved...

knowing this

A It requires the slow flow of heat energy and information is not lost --> FALSE

B The loss of heat energy from the sample becomes the gain in heat energy of the water bath --> TRUE

C It operates under standard isobaric conditions -- >Not really, we do not need P to be isobaric
