Step 3: Prepare the Spreadsheet. In this tutorial, we will create a very simple macro to change the color, size and boldness of text. In your spreadsheet, type in some text in any of the cells. We will later record a macro to change the formatting of this text.
The average cooling capacity of a dorm fridge is somewhere around 150 BTU/hr, that is, it is capable of moving 150 BTUs of heat in 1 hour, regardless of how efficient (or inefficient) it is in terms of energy usage.

The most common method is to unplug the refrigerator or freezer, prop the door open and allow the ice to melt on its own. However, this method may take up to a day to defrost the appliance completely.
