Yes, but it is so hard as not to be worth it.
No.It is chemical change so it is irreversible
because it is
It is irreversible
Melting is a phase change, which is entirely controlled by temperature (pressure is also relevant but under normal circumstances, air pressure is approximately constant). Curdling is a chemical change. The process that leads to a particular chemical is much more complicated than a change in temperature.
Milk curdling is a chemical change.
Typically, yes. Butter is a mixture of fat and milk solids. Once melted the fats separate from the milk solids. 'Clarified' butter, or ghee, is the separated butter fat, often used in Indian cooking, as a canning sealer, or as a dip for steamed shellfish. Clarified butter, once separated from the milk solids, does not require refrigeration to keep it from going rancid, however, it must be kept cool to maintain its solidity.
No because you can't get the vinegar back to it's original state because some of the bacteria has gone inside the milk
when milk curs it is a chemical change. A physical change is change in form, which is revesrable. Like water being frozen then thawed. A chemical change is irreversible, and involves a change in the chemical make up. What is happening is a new compound is being formed by the milk reacting with the air and such.
the changes which can be reversed by reversing the conditions are reversible changes. the changes which cannot be reversed by reversing the conditions are irreversible changes.
Curdling.
the protein in the milk is denatured, therefore it cannot return to its original structure. the tertiary and quaternary structure of the original protein changes, bonds are broken and others reformed, these cannot be changed. the process is similar to that of cooking an egg, once it has been cooked it cannot change back to its raw state.
A sentence could be "I knew the milk was off because it was curdling"
Kind of... if you boil milk, then some of it evaporates, so... sort of :)
ya it really effect it is the main source of curdling it.
The souring and curdling of milk is caused by bacteria.
