What is a system in thermodynamics?

Back

A system is a specific portion of matter or space that is being studied, while everything outside of it is considered the surroundings.

Front

What are surroundings in a thermodynamic context?

Back

Surroundings are everything outside the system that can exchange energy or matter with the system.

Front

How do you identify a system and its surroundings in an experiment?

Back

The system is the part of the experiment you focus on, while the surroundings include everything else that interacts with the system.

Front

What is the significance of bond energy in molecules?

Back

Bond energy is the amount of energy required to break a bond between two atoms; it indicates the stability of the molecule.

Front

How do you determine the number of atoms in a molecule?

Back

The number of atoms in a molecule can be determined by adding the subscripts in its chemical formula.
