Can carbon dioxide change from a solid directly into a gas?
Yes, this is why solid carbon dioxide is often called "dry ice." Instead of melting, it sublimes directly from a solid into a gas.
Can a solid change its state of matter straight to a gas?
Yes it can. It is called sublimation. Solid carbon dioxide (dry ice) sublimes at room temperature.
Is freezing carbon dioxide a chemical change or physical change?
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
Does plants change carbon monoxide to carbon dioxide?
plants do not change carbon monoxide into carbon dioxide. they, on the other hand, convert carbon dioxide in to oxygen.
What colour would Carbon dioxide change limewater to?
Carbon dioxide.
What happens when a solid sublimes?
When ice sublimes, the molecules at the edge of the ice escape into the gas phase as water vapor. The solid phase thus turns directly into the gas phase without an intermediary liquid phase. Ice sublimes quite slowly under normal conditions, but dry ice (solid carbon dioxide) sublimes readily at everyday temperatures and pressures.
Is sublimation a chemical change?
Nope, it's physical. When a material sublimes or sublimates, it changes state from a solid to a gas. Carbon dioxide does this, and so do mothballs. Nothing new is created; it's just a state change, so it's physical.
Which organs are oxygen and carbon dioxide changed?
Oxygen and carbon dioxide change in the lungs.
When a substance changes from a solid to a gas?
The change in state from a solid directly to a gas is called sublimation. An example is frozen carbon dioxide which changes directly into gaseous carbon dioxide without going through a liquid phase.
Does dry ice go through a physical change or chemical change?
It is a physical change (phase change). Dry Ice is frozen carbon dioxide gas. At atmospheric pressure, liquid CO2 is unstable. So the frozen solid "sublimes" turning directly from a solid to a gas (absorbing heat from around it).
What must be done to carbon dioxide gas to change it to solid?
the cold air can change the carbon dioxide gas to a solid
If you could break up a carbon dioxide molecule would you still have carbon dioxide?
Although the molecule is broken up it does not change the fact that it is carbon dioxide. Therefore you still have carbon dioxide.
