Which method for measuring fat uses water displacement by combining fat with water in a liquid measuring cup?

• A. Yield
• B. Portion size
• C. Water displacement method
• D. Temperature, time, and equipment

Answer: (C)

Measuring fat by water displacement uses the idea that a solid’s volume can be found by how much water it pushes aside when submerged in a liquid. You fill a liquid measuring cup to a known mark, note the starting volume, then fully submerge the fat piece. The water level rises to a new mark, and the difference between the two readings is the fat’s volume. This method is especially useful for irregularly shaped fats or when you need a precise volume rather than an approximate scoop. If you need weight from that volume, you can convert using fat’s density. Other options don’t involve determining a solid’s volume through water displacement, so they don’t fit this measurement method.
