One kilogram of graphite is burnt in a closed vessel.The same amount of graphite is burnt in an open vessel.Will the heat evolved in two cases be same or different?

Explanation

To determine whether the heat evolved from burning 1 kg of graphite in a closed vessel is the same as that in an open vessel, we can analyze the situation step by step.

### Step 1: Understand the combustion of graphite
When graphite (carbon) is burnt, it reacts with oxygen to form carbon dioxide (CO₂). The reaction can be represented as:
\[ C + O_2 \rightarrow CO_2 \]

### Step 2: Consider the amount of graphite
In both scenarios, we are burning the same amount of graphite, which is 1 kg. This means the amount of carbon being oxidized is identical in both cases.
