What happens when methane undergoes combustion in systems A and B respectively? Adiabatic system A Diathermic container System B
- Temperature rises; Temperature remains same
- Temperature remains same; Temperature rises
- Temperature falls; Temperature remains same
- Temperature falls; Temperature rises
Correct answer: Temperature rises; Temperature remains same
Solution
In an adiabatic system, the combustion of methane leads to an increase in temperature due to the heat generated being retained within the system. In contrast, a diathermic container allows heat exchange with the surroundings, so the temperature remains constant as the heat produced is dissipated.
