This is a loaded question. You have to concider a few things into this that are not as simple as one unit of beef pattieFirst, we know that it is a pattie (that is the given unit)But patties are available in different sizes, usually a fraction of a poundIf a pound weighs 16 ounces (which is a given)and you want to divide patties into that, then we need to know the size pattiethere are a few standards 1/2 pounder, 1/4 pounder, 1/3 pounder etcso therefore16 ounces/ 1/2 pounder = 16/.5=8 ounce pattie16 ounces/ 1/4 pounder = 16/.25=4 ounce pattie16 ounces/ 1/3 pounder = 16/.33=5.333 ounce pattiethis still can change depends upon if it is before or after cooking where some moisture goes away from the heat and the pattie will loose weight
No. That is a chemical change. In a physical change, their is no change in chemical composition forming one or more new substances.
