Answer 5

In nonrelativistic classical mechanics, a closed system is a physical system which doesn't exchange any matter with its surroundings, and isn't subject to any force whose source is external to the system.

Answer 6

so A

Answer 7

If water is out of the system (inside the bucket), it will not be an opens system.
A) is sorta correct, but water only evaporate (liquid to gas) when it gets really hot, and not cold.
It freezes when it gets cold.

Answer 8

D

Answer 9

or C

Answer 15

Frozen ice has water molecules in it.
It is just water in solid form.

Answer 16

In other words, why can water not be inside a bucket for so long?
If water is leaving the bucket, external forces are created.
The question is asking why does water stay in a bucket for a short amount of time?

@Shalante

Answer 24

Explanation?

Answer 25

The reason is that a closed system has nothing going in or out and water retains energy very well also water it polar so it is attracted to itself. It doesnt like contact with other things.

Answer 26

So if water spills, then it wont be closed for so long.

Answer 27

A bucket of water would eventually dump it out in a short amount of time.

Answer 28

Mass never disappears. Water contains only water unless stated otherwise. The spill shouldn't effect the system, so let's go with A.
