What happens to a substance as it under goes a phase change?
A change from gas to liquid, from solid to liquid, from liquid to gas, etc.
What phase Change?
A phase change occurs when a material goes from a gaseous state to a liquid state, a liquid state to a solid state, or the above in reverse order.
Can carbon dioxude change directly from the solid phase to the gas phase?
Yes, it has no liquid phase at standard atmosphere pressure and it goes directly from solid to gas - this process is called sublimation
What is the phase change that occurs when a solid goes directly to a gas without melting first?
The phase change is called sublimation. In this process, a solid changes directly into a gas without passing through the liquid phase.
What type of change is it when a solid turns into a gas?
Sublimation - the process by which a substance goes directly from the solid to the gaseous state without passing through the liquid state.
When a substance under goes a physical change its?
The classical example is water with 3 phases: solid, liquid, gas. The transition is called change of phase
What is a substance when it under goes a physical change?

Is it true melting is considered an sublimation change because energy is gained by substance as it changes stae?
Melting is a phase change in which a substance changes from the solid state to the liquid state. Sublimation is a phase change in which a solid moves directly into the gas phase. Both melting and sublimation are two types of physical change.
When a substance goes from a gas to a liquid it goes through a?
Phase change.
Evaporation referes to the change of state from?
Evaporation is the phase change of matter when it goes from liquid to gas. The opposite phase change is condensation.
What is the change of state from solid to a gas called?
If a gas changes into a solid, without becoming a liquid first, it goes through deposition.
Is a change in phase a chemical or physical change?
A phase change is when matter changes into another form but keeps its properties.For example, ice melting into water is an example of the phase change melting.The main types of phase changes are melting, vaporization, freezing and condensation.- Melting is when a solid turns into a liquid.- Freezing is when a liquid turns into a solid.- Vaporization is when a liquid turns into a gas. Boiling is a form of vaporization when the change takes place throughout the liquid. Evaporation is a form of vaporization in which the phase change takes place only at the top of the liquid.- Condensation is when a gas turns into a liquid.- There is also sublimation, which is when a solid turns directly into a gas.- Deposition is when a gas turns directly into a solid.
