The metal would tend to contract in size. One technique to remove a gear from a shaft is to cool the shaft while heating the gear. The shaft contracts a bit while the gear expands a bit which can make the gear easier to remove. Also, dry ice (CO2) would not oxidize metal as water ice (H2O) would.
I just had this question for a chemistry and it is a physical change
The process of dry ice sublimating, or turning directly from a solid to a gas, is a physical change. No new substances are formed, just a change in the physical state of the dry ice from solid to gas.
A physical change
Melting dry ice is a physical change because it is a change in state from solid to gas without altering the chemical composition of the substance.
A physical change. It's chemically still CO2, whether solid or a gas.
It isn't. Answer --> It is an example of phase change and thus a physical change. Not a chemical change
It is a physical change. Being changed from wet to dry.
Dry ice doesn't "turn into smoke". Dry ice causes moisture in the air to condense, forming fog. This is a purely physical, not chemical, change.
The process is a physical process and the actual change is a physical change.
Physical change, called sublimation. It still stays CO2
The melting of ice is a physical change. The physical change include physical change include sublimating dry ice, boiling water, crushing an aluminum can or breaking a glass bottle.
Yes
