Question

A tightly sealed glass jar is an example of which type of system?

A.Connected
B.Closed
C.Open
D.Isolated

Answer 1

B. Closed, because you can't call it isolated because your not isolating the jar, plus the jar is nether connected or opened. Hope that helps!

Answer 2

The answer is a closed system, B.

A closed system is a system where the amount of matter in it stays the same, but energy can go in and out of the system.

It is a closed system because the amount of matter inside the jar stays the same, as long as it is closed, but energy (most likely heat) would still be able to go in and out of the jar.

The answer is a closed system, B.
