N is the same as Kg/m/s^2. False...K.g/M/s^2.?

It is easier to sweep with a brown if your hand is further up on the handle. true?

a screw with fewer threads is easier to use than a screw of the same size with more threads.-true?

water at 4^0C is lighter than at 4.1^0C. True?

ice can release heat-true?

1) False. A Newton is a kilogram meter per second squared (kgm/s²).

2) True. Torque = Force x radius. More radius means less applied force.

3) Not sure, although most of these you could look up online.

4) The water would be less dense at 4 deg C, I suppose, but not lighter. That would have to do with gravity.

5) Only true if the surroundings are colder than the ice itself. Heat migrates from warmer to colder.

More dense at 4 deg C. That's the maximum density temperature for water. You are right it will be not lighter though.
