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.
How is an endothermic phase change different from an exothermic phase change? An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization). In an exothermic phase change the substance releases energy tâ¦o its surroundings (freezing, condensation).. 10 people found this useful. Norvellwisdom. 12,735 Contributions.
I am trying to achieve an understanding of this occurances to be able to recognize them myself. Thanks. Terry Holbrook. When trying to classify a process as exothermic or endothermic, watch how the temperature of the surroundings changes. An exothermic process releases heat, and causes the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.
