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.
No, mass remains constant during a phase change. The number of particles in the substance does not change, only their arrangement or motion.
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.

What type of change is it when a solid turns into a gas?
It is a phase change called sublimation, where a solid transitions directly into a gas without passing through the liquid phase.
How can the temperature of a substance remain the same even if the substance is absorbing thermal enerrgy?
The temperature of a substance can remain the same during absorbing thermal energy if the substance is undergoing a phase change, such as melting or boiling. During a phase change, the absorbed thermal energy goes into breaking intermolecular bonds rather than increasing the temperature. Once the phase change is complete, the temperature will resume rising as the substance absorbs more thermal energy.
What is phase change solid to gas?
The phase change from a solid to a gas is called sublimation. This process occurs when a substance goes directly from a solid state to a gaseous state without passing through the liquid state. Examples include dry ice (solid carbon dioxide) sublimating into carbon dioxide gas at room temperature.
What best describes the change directly from the solid phase to the gas phase?
The change directly from the solid phase to the gas phase is called sublimation. This transition occurs when a substance goes from a solid state to a gaseous state without passing through the liquid state.
Is Condensation thermal energy?
Condensation is a phase change process where a substance goes from a gas to a liquid state, releasing thermal energy in the form of heat. This type of energy transfer is known as heat of condensation.
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 is the change that a substance goes through to make another substance?
Chemical change
What happens when substances goes through a phase change?
During a phase change, the substance undergoes a physical transformation without changing its chemical composition. Energy is either absorbed or released as the particles rearrange themselves into a different arrangement or state of matter. This process can result in changes in temperature, volume, or pressure depending on the specific phase change.
What type of change is it when a solid turns into a gas?
It is a phase change called sublimation, where a solid transitions directly into a gas without passing through the liquid phase.
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 is taking place when a substance goes from a gas to a liquid?
The phase change when a substance goes from a gas to a liquid is called condensation. This occurs when the temperature of the gas decreases, causing the gas particles to lose energy and come together to form a liquid.
Is it true melting is considered an sublimation change because energy is gained by substance as it changes stae?
No, melting is not considered a sublimation change. Melting is a phase transition in which a substance goes from a solid to a liquid state by absorbing heat energy. Sublimation is the direct transition from solid to gas without passing through the liquid state.
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.
What changes take place when a substance goes through a phase change?
During a phase change, the arrangement of the particles changes while the chemical composition remains the same. Energy is absorbed or released, causing changes in temperature and state. Phase changes include processes like melting, freezing, vaporization, condensation, and sublimation.
