Changing the energy of a system

[Amy Kumar 1I]

What are the three ways to change the energy of a system?

[Shimei_2F]

The three ways to change the energy of a system is heat, work, and mass flow.

[KHowe_1D]

Heat, mass flow, and work are the ways to change the energy of a system.

[Sydney Pell 2E]

To change the energy of a system, you can add or remove the amount of the substance in the system, although this only applies to open systems.

The second way to change energy is heat or cool the system (for a closed system).

The third way to change the energy of a system is to do work on the system/let the system do work on the surroundings, such as compressing or moving out a piston in a closed system.

[Mulin_Li_2J]

1, Add or Remove the amount of substances from a system
2, Heat or cool the system
3, Do work on the system, or let system do work on the surroundings.

Note that the energy of the system refers to the internal energy denoted as U.

Hope this can help!

[Sean Tran 2K]

You can change heat, mass, or do work on the system.

[Jacob Villar 2C]

Heat, mass flow, and work.

[Niharika 1H]

The energy of a system can be changed through heat, work, and mass flow.
