Does the mass change as a substance goes through a phase change?

Mass is conserved. Volume changes slightly, so density changes as well, but mass remains the same.

∙ 13y agoA phase change does not result in a mass change. The density of a substance may change, but the mass will not. If a kilogram of water changes phase into ice, there will be a kilogram of ice. The volume of the ice will be greater than the volume of the water, but one kilogram is one kilogram.

∙ 8y agoThe mass of a substance does not change once it melts, or turns from a solid to a liquid. If the mass of an ice cube is 50 grams, the mass of the water resulting when the cube melts will also be 50 grams. Melting (or fusion) is a phase change, not a chemical change.

∙ 13y agothe mass stays the same but the volume will change.
the density will change as well

∙ 12y agoyes, water in ice form is less dense the water in liquid form. that's why ice cubes float in a glass of soda, or on a pond or lake oly the top freezes and the ice doesnt sink to the bottom.

How can the law of conservation of matter be demonstrated?
When ice melts, its mass doesn't change. It just goes through a phase change and becomes water. Again, when water evaporates, it goes through a phase change and becomes water vapor. The conservation of mass is hence proved.
What does an ice cube go through when it is melting?
The bonds between water molecules are weakened.
What doesn't change with changes in gravity?
Nothing does, because there is no such thing as "an unbalanced force",so that scenario can never occur.When an unbalanced group of forces acts on an object, the speed or directionof the object's motion can change, but its mass does not change.The mass of the object.
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.
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.
When a substance goes from a gas to a liquid it goes through a?
Phase change.
What is the process when a substance goes from a liquid to gas?
Evaporation, which is a phase change.
What happens when substances goes through a phase change?
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
What is the change that a substance goes through to make another substance?
Chemical change
What phase change is taking place when a substance goes from a gas to a liquid?
condensation
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 dry ice goes through what phase change?
The phenomenon is called sublimation.
What happens When a substance goes through a physical change?
The Substances die
Since ice is frozen water when it melts does it become new matter?
Answer: When any substance goes through a phase change only its state is changed, it is still the same combination of element's.

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
