Oxidizing food for energy-physical change?
Oxidation is a chemical process.
Is mercury expanding in a thermometer a chemical or physical change?
Physical. The mercury doesn't change.
Is mercury being heated to produce mercury vapor a physical change?
YES, because evaperation is the same as changing it in to a gas which is a physical change.
Is it a physical or chemical change when the liquid mercury in a thermometer expands as it is heated?
physical change
Is grinding of mercury and iodine physical change or chemical change?
Grinding mercury or iodine would be a physical change - you are changing the shape but not the element. However, grinding mercury with iodine may be a chemical change if you end up with mercury iodide through a chemical reaction. Incidentally, I don't recommend actually trying this - mercury is a liquid at room temperature (it is also called quicksilver for this reason) and is very toxic to humans.
Is oxidizing Mercury physical or chemical change?
Both. A chemical reaction occurs & a physical change is noticeable.
Is oxidizing a physical or chemical change?
chemical change:)
Is oxidizing physical change?
Oxidation and reduction are chemical changes.

Oxidation is a chemical process.
Is mercury expanding in a thermometer a chemical or physical change?
Physical. The mercury doesn't change.
Is darkening of cut apple physical change?
It's a chemical change because the apple is oxidizing. It turns brown, because of the oxygen, hence the word " oxidizing".
Is the Statue of Liberty a physical change or a chemical change?
No its a chemical change because the acid in the rain reacts with the copper in the statue having a reaction oxidizing it and turning it green.
Is mercury being heated to produce mercury vapor a physical change?
YES, because evaperation is the same as changing it in to a gas which is a physical change.
Is it a physical or chemical change when the liquid mercury in a thermometer expands as it is heated?
physical change
Is heating mercuric oxide a physical or chemical change?
This is a chemical reaction; oxygen is released.
How is freezing mercury a reversable physical change?
During freezing the chemical nature of mercury remain unchanged.
