Question

Q. 3 A mixture of hydrogen and oxygen is enclosed in a rigid insulating cylinder. It is ignited by a spark.
The temperature and the pressure both increase considerably. Assuming that the energy supplied by the spark is
negligible, what conclusions may be drawn by application of the first law of thermodynamics?​

Answer 1

Answer:

Also it is given that system is insulated and there is considerable increase in the temperature and pressure we ignition of mixture of hydrogen and oxygen as adiabatic expansion. Where work is done by system on surrounding and internal energy of system decreases.
