The weight of the water won't change. The density will.
Water reaches its smallest volume at about 4C, after which it's volume begins to increase. Water are 5C has a higher density than water at 2C, but it is not heavier. "Heavy" depends on g.

1- I do not know.
2- true as it depends on how the strings are set up. The normal ways of setting up a block and tackle would have this as false though. There is a configuration for three strings which is equal to a specific four string configuration.
