Text SolutionText solutionverified iconVerified

While lighting a bulb through a battery, the chemical energy of the battery gets converted into the electric energy which further gets converted into light energy along with heat energy. That is why after lighting a bulb for some time, it gets heated up.
One form of energy can be transformed to another form but it cannot be created or destroyed.

(i) By action from Water Superheated steam is passed over white hot coke at about . Steam combines with white hot coke to form a mixture of equimolecular amounts of carbon monoxide and hydrogen. This mixture is called water gas. During the process, an endothermic reaction takes place. (ii) Reduction of steam to hydrogen by carbon monoxide: The water gas so obtained is mixed with excess steam, and passed over a mixture of ferric oxide (catalyst) and chromium oxide (promoter), at an elevated temperature . Steam is reduced to hydrogen and carbon monoxide is oxidised to carbon dioxide yielding more hydrogen. Prodicing heat As a resuit it catches the
