JEE Mains · Chemistry · STD 11 - 5. Thermodynamics and thermochemistry
What happens when methane undergoes combustion in systems A and B respectively?
| System \(A\) | System \(B\) |
| Temprature rise | Temprature remains same |
- A
System \(A\) System \(B\) Adiabatic system Temprature rise - B
System \(A\) System \(B\) Temprature falls Diathermic system - C
System \(A\) System \(B\) Temprature falls Temprature remains same - D
System \(A\) System \(B\) Temprature remains same Temprature rise
Answer & Solution
Correct Answer
(A)
System \(A\) System \(B\) Adiabatic system Temprature rise
Step-by-step Solution
Detailed explanation
Adiabatic boundary does not allow heat exchange thus heat generated in container can't escape out thereby increasing the temperature. In case of Diathermic container, heat flow can occur to maintain the constant temperature.
