Question

Two different liquids are poured into a jar until it is half full. The jar is then sealed shut and shaken. The liquids undergo a chemical reaction that releases thermal energy and also

emits a new gas into the far. The new gas increases the pressure inside the jar. After the far is sealed, it is an example of an)

Answer 1

A closed system.

Step-by-step explanation:

The three major types of system are: open, closed and isolated. Open system interacts with its surroundings with respect to its particles and energy. A closed system interacts with its surroundings with respect to energy but not its particles. While an isolated system does not interact with its surroundings in any way.

Therefore, after the jar is sealed, it is an example of a closed system. This is because the emitted gas could not escape into the surroundings, but thermal energy was emitted into its surroundings after the chemical reaction has taken place.
