While milk is produced naturally by cows, the milk that we buy in the supermarket has been subjected to a number of different processes such as pasteurisation (which sterilises it) and homogenisation (which mixes the cream and the milk together uniformly). Would you describe milk as natural or processed? Explain your answer.

Explanation:

Ultimately, milk can be described as both. The actual description depends on the individual and/or company involved. For example, in many places milk if extracted from cows, bottled, and delivered to the end consumer. In this case, milk would be considered as natural because nothing has been done to change its nutritional composition. This changes when companies begin to pasteurise and homogenize the milk so that it has a longer shelf life and create different variations. The milk in this case no longer has the same nutritional composition and has been altered, and is therefore considered as processed.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
