Environment

from class:

College Physics III – Thermodynamics, Electricity, and Magnetism

Definition

The environment in thermodynamics is everything outside the system being studied. It interacts with the system through exchanges of energy and matter.

congrats on reading the definition of environment. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. The environment and the system together make up the universe in thermodynamic studies.
  2. Energy can be transferred between a system and its environment in the form of heat or work.
  3. The boundary separating the system from the environment can be fixed or movable, depending on whether work is done.
  4. In an isolated system, there is no interaction with the surrounding environment (no exchange of energy or matter).
  5. Changes in a system's internal energy are influenced by interactions with its environment.

Review Questions

  • What constitutes the 'environment' in a thermodynamic problem?
  • How does energy transfer occur between a system and its environment?
  • What happens at the boundary between a thermodynamic system and its environment?
