Question

Steam engine is not extensively used because ......

• A. it is bulky
• B. it takes long time to generate the steam
• C. high pressure of steam may burst the boiler which is dangerous
• D. all of above

Answer 1

The correct option is D all of above

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. In simple terms, the steam engine uses the expansion principle of chemistry, where heat applied to water transforms the water to steam. and then pushes a piston (cylinder). This pushing force is typically transformed, by way of a connecting rod and flywheel, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine.

Steam engine is not extensively used because it is bulky,it takes long time to generate the steam,high pressure of steam may burst the boiler which is dangerous

Hence option D is correct.
