Ascientist put red blood cells in water that contained salt. over time, the red blood cells burst. what is most likely true?

that the salted water osmolarity was bellow 300mOsm/L.

Explanation:

A solution with osmolarity bellow 300mOsm/L is known as hypotonic and will cause a cell to swell and eventually burst if equilibrium is not reached

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.
