(1/4 pound) but its volume is 1/2 cup or 8 Tbsp. So two sticks of butter would equal 8 oz. (1/2 pound) or 1 cup (16 Tbsp.). According to your conversion chart, the correct substitution would be 3/4 cup olive oil.
Humidity Humidity is the term for the amount of water vapor in air There are from GEO 1013 at The University of Texas at San Antonio- San Antonio
Water activity or a w is the partial vapor pressure of water in a substance divided by the standard state partial vapor pressure of water. In the field of food science, the standard state is most often defined as the partial vapor pressure of pure water at the same temperature.ater migrates from areas of high a w to areas of low a w. For example, if honey (a w â 0.6) is exposed to humid air (a w â 0.7), the honey absorbs water from the air. If salami (a w â 0.87) is exposed to dry air (a w â 0.5), the salami dries out, which could preserve it or spoil it.
