Prep the perimeter. Hand-sand or palm-sand the perimeter of the floor with coarse 180-grit sandpaper. Rub out 4 to 6 inches (10.2 to 15.2 cm) from the edge of the baseboard so that you're sure to cover the areas your mechanical floor sander can't get to. To make a wood paste, mix sawdust with a small amount of white glue to create a paste. 2  Apply paste over the nails with a putty knife and allow to harden before sanding flush with the rest of the floor.

In an exothermic phase change the substance releases energy tâ¦o its surroundings (freezing, condensation).. 10 people found this useful. Norvellwisdom. 12,735 Contributions.
A reaction in which heat energy is absorbed is said to be endothermic. You can show this on simple energy diagrams. For an exothermic change: Notice that in an exothermic change, the products have a lower energy than the reactants. The energy that the system loses is given out as heat.
