Based on the law of conservation of energy, how can we reasonably improve a machine’s ability to do work? move the machine to a different gravitational field. increase the friction between its moving parts. reduce the friction between its moving parts. redefine the machine’s system boundaries.

The bubbles in a carbonated soft drink are produced when carbonic acid decomposes to form carbon dioxide and water. in a closed system, this equilibrium exists as why does a carbonated soft drink lose carbonation when the container is left open? a.water evaporates, which favors the formation of h2co3. b.pressure decreases, which favors the formation of h2co3. c.the open container warms up, which causes more gas to escape. d.co2is removed, which favors the formation of h2co3.
