Mass is conserved. Volume changes slightly, so density changes as well, but mass remains the same.
A 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.
The 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.
the mass stays the same but the volume will change.
the density will change as well
yes, 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.
It stays the same
No, however it density will change.
no
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.
The bonds between water molecules are weakened.
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.
Sublimation - the process by which a substance goes directly from the solid to the gaseous state without passing through the liquid state.
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.
Phase change.
Evaporation, which is 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.
Chemical change
condensation
A change from gas to liquid, from solid to liquid, from liquid to gas, etc.
The phenomenon is called sublimation.
The Substances die
Answer: When any substance goes through a phase change only its state is changed, it is still the same combination of element's.
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.
The classical example is water with 3 phases: solid, liquid, gas. The transition is called change of phase
