5 Questions
What is the definition of work in physics?
Work in physics is defined as the force (F) that produces the movement of an object times the distance moved (d).
Give an example of expansion work.
An example of expansion work is a gas expanding in a cylinder fitted with a piston pushing out against the atmosphere.
What is non-expansion work?
Non-expansion work is work that does not involve a change in volume of the system.
How is expansion work related to the volume change of a system?
Expansion work arises from a change in the volume of a system, such as a gas expanding in a cylinder fitted with a piston pushing out against the atmosphere.
Provide an example of non-expansion work.
An example of non-expansion work is a chemical reaction in a battery causing an electrical current to flow, or our bodies performing non-expansion work in various activities.
