Specific gravity of milk at 60° F is ______ m/s².

The correct answer for the specific gravity of milk at 60° F is indeed 1.032. Specific gravity is a measure of the density of a substance compared to the density of water, which is defined as having a specific gravity of 1.000. The specific gravity of milk can vary slightly based on its composition, including fat, protein, and carbohydrate content, but it typically falls within the range of 1.030 to 1.034 at that temperature.

A specific gravity of 1.032 indicates that milk is denser than water, which is consistent with the expected properties of milk due to its various components. Understanding the specific gravity of milk is important in the dairy industry because it can affect quality assessment, processing, and pricing.

The other values provided, such as 1.025, 1.030, and 1.040, while they can represent the specific gravity of certain fluid samples, do not align with the average specific gravity of milk at the specified temperature, which is why they are not regarded as the correct answer. Choosing 1.032 reflects an accurate understanding of the standard measurement for milk's specific gravity under those conditions.
