Two scientists failed to report unusual findings when they shared their results from a recent science experiment. why is this not scientifically sound?

A scientist always needs to report their observations and outcomes truthfully. The scientific experiment refers to a fact determining procedure, which is done in a step by step manner in order to answers the queries associated with science.  

Any bias like the use of undesired equipment, skipping the protocol, and manipulating the observations and outcomes cannot be regarded scientifically appropriate.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
