No the heat in the two cases will be different
The heat in the closed vessel will be more as the will not able to escaped in the atmosphere

Answer: it will be the same.
Explanation:
When 1kg of graphite is burned in a closed vessel and the same amount of sample is burned in another vessel. The het evolved will be same in both the cases as ∆n=0 in both cases. ∆ ng value is equal to product gaseous molecule-reactant gaseous molecule. If ∆n was different the amount if heat evolved would not be same.
Closed container would have Cv
And open container would have Cp.
The amount of gas evolved in open container would be more than closed container in that case.
