Describe a revisionary movement and provide an example.

Explanation:

Revisionary movements aim to improve, or revise, some part of society through social change. Some examples include the women's suffrage movement, the civil rights movement, and the environmental movement.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:

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.
