Achemical reaction is occurring inside a beaker and the temperature of the beaker is monitored. what would the contents of the beaker be referred to as? the system the surroundings the boundary the universe

The system is the Answer

Explanation:

System is the region which is taken into consideration.

While we perform a chemical reaction the system is the substance taken in the container.

So, A thermodynamic system is the amount of matter or the region in universe which is under the study.

The region outside the beaker are called as surroundings.

The beaker (the surface which separates the system from its surroundings) is said to be the boundary

System + surroundings = universe

it would be a gas formation
