Chemistry - Thermodynamics - I Question with Solution | TestHub

Bomb calorimeter is commonly used to find the heat of combustion of organic substances which consists of a sealed combustion chamber, called a bomb. If a process is run in a sealed container then no expansion or compression is allowed, so$\text{w=0}$and$\mathrm{\Delta }\text{U=q}$.
$\mathrm{\Delta }\mathrm{U}<0,\mathrm{w}=0$
