What is the phase change involving no liquid?
sublimation. an example would be dry ice. dry ice changes from a solid to a gas without going through the liquid phase.
Name and describe the phase change that occurs when dry ice is placed in an opened container at room temperature?
Dry ice (solid CO2) at room temperature changes from a solid to a gas without going through the liquid phase. This is called sublimation.
When a substance goes directly from a solid state to a gas state as dry ice does .?
It's called sublimation. Its undergoing a phase change. -APEX:)
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 pieces of dry ice become smaller through the process of condensation?
Pieces of dry ice, otherwise known as solid carbon dioxide, become smaller through the process of sublimation. This is the physical change of matter from solid to gas. When combined with water, a mix of humid air and CO2 is created. The water then condenses creating fog.

Do pieces of dry ice become smaller through condensation?
No, dry ice pieces do not become smaller through condensation. Rather they become smaller through sublimation, the physical change of matter from a solid phase to a gaseous phase. Condensation is the physical change of matter from a gaseous phase to a liquid phase, such as when you blow on your eyeglasses to fog them up so you can wipe them clean. Since dry ice is solid carbon dioxide, it cannot undergo condensation.

Why use dry ice to make stage effect instead of water ice?
Dry ice goes through one change to make "fog", but water ice has to go through two changes to become a gas.You could use water ice to make fog, but it would have to go through the liquid phase before it evaporates or boils. But dry ice, instead of melting and evaporating, will go through what is called sublimation, which is the change of matter of solid to gas.
What describes the phase change that occurs when dry ice is placed in an open container at room temperature?
the phase change is from solid into gas,and this phase change is called sublimation.
Why when dry ice is exposed to the air does it change to a vapor. This is a example of what?
sublimation
Why is dry ice disappearing a chemical change?
It isn't. Answer --> It is an example of phase change and thus a physical change. Not a chemical change
Is dry ice subliamating into carbon dioxide a chemical change?
no. a phase change is ALWAYS a physical change in the substance.
What does sublimation means in?
Sublimation is where a substance goes from solid to gas without passing through a liquid phase. Two common products that sublimate are dry ice and naphthalene mothballs.
What is dry ice and how is it connected to sublimation?
Dry ice is solid carbon dioxide. Carbon dioxide goes from a solid phase to a gaseous phase without becoming a liquid and that transition is called sublimation.
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).
