Explanation:

Question 2

In thermodynamics, a system is the part we focus on, and surroundings are everything else. When water freezes in a freezer, the freezer is part of the surroundings relative to the water (the system). The universe is system + surroundings, and the freezer isn't the system (water is the system here). So the freezer is the surroundings.

When water freezes in a freezer, the water is the system. The surroundings are everything outside the system (water), which includes the freezer and everything else. "Everything that isn't the water" includes the freezer and other parts, so this is correct. The freezer is part of surroundings, but the option "everything that isn't the water" is more comprehensive.

A closed system in thermodynamics is defined as a system that allows exchange of energy (like heat, work) with the surroundings but does not allow exchange of matter. An open system allows both, isolated allows neither. So a closed system allows only energy but not matter exchange.

Answer:

A. the surroundings
