Phase change doesn't effect the mass of substance. However, it cause drastic change of density and the weight of substance may change due to buoyancy force.

What The heat of fusion of a substance is the energy measured during a?

The heat of fusion of a substance is the energy required to change a unit mass of the substance from a solid to a liquid state at its melting point. It is measured during the phase transition process when the substance absorbs heat energy to break the intermolecular forces holding its particles together in the solid state.


Does the density of gold change when you melt it into liquid form?

No, the density of gold remains the same when it is melted into liquid form. Density is an intrinsic property of a substance that depends on its mass and volume, which do not change during a phase change like melting.


What happens to the overall mass of a substance when it changes state?

The overall mass of a substance remains the same when it changes state. The mass is conserved during physical changes like melting, freezing, vaporization, or condensation. This is because the number of atoms or molecules in the substance does not change during a change in state.


How will the mass of a pure substance be affected when the volume is increased?

The mass of a pure substance will remain constant even if the volume is increased. The mass of a substance is an intrinsic property that does not change with changes in volume.


Why does the density of a substance not change with the sample size?

The density of a substance does not change with the sample size because density is an intrinsic property of the material, determined by its mass and volume. As you increase the sample size, both the mass and volume of the substance increase proportionally, resulting in no change in density. This relationship is described by the formula density = mass/volume, which remains constant regardless of the amount of the substance being measured.

When a substance undergoes a phase change it still has a definite A mass B shape C volume D temperature?

C. volume. During a phase change, the substance's volume remains constant even though there may be a change in its mass, shape, or temperature.


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.


What is the energy per unit mass required to complete a phase change called?

The energy per unit mass required to complete a phase change is called the latent heat. It represents the energy needed to change the state of a substance without changing its temperature.


What property of a substance does not change when it turns into gas?

The chemical identity of a substance remains the same when it turns into a gas. The type of atoms and their arrangement within the substance do not change during the phase transition from liquid to gas.


How is the mass of a liquid substance affected after it boils?

When a liquid substance boils, it undergoes a phase change from liquid to gas. During this process, the mass of the substance remains unchanged, as the molecules transition from the liquid phase to the gas phase without any loss or gain of matter. However, if the gas escapes the container, the mass of the remaining liquid will decrease. Thus, the mass of the entire system depends on whether the gas is retained or allowed to escape.


What is the effect on a chemical change on the mass of matter?

chemical changes disturbs the structure of the substance and hence reduce the mass....thx...with best regards..


What The heat of fusion of a substance is the energy measured during a?

The heat of fusion of a substance is the energy required to change a unit mass of the substance from a solid to a liquid state at its melting point. It is measured during the phase transition process when the substance absorbs heat energy to break the intermolecular forces holding its particles together in the solid state.


In what state of matter has mass and it and it is the same each time?

Mass is a property that remains constant in all states of matter: solid, liquid, gas, and plasma. The total mass of a substance does not change when it undergoes a phase change because mass is a measure of the amount of matter in an object.


How does the conservation of matter relate to phase changes?

The conservation of matter principle states that matter cannot be created or destroyed in a chemical reaction. In the context of phase changes, the total mass of a substance remains the same before and after a phase change occurs. This means that during a phase change, while the substance may change its physical state (solid to liquid, liquid to gas, etc.), the total amount of matter stays constant.


What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?

The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.


In what phase would a substance with a volume of 25.00mL and a mass of 78.05g be at STP?

Gas


Can latent heat level be measured?

Latent heat cannot be measured directly with a sensor. It is the amount of heat energy that is absorbed or released during a phase change (e.g., melting, boiling). However, it can be calculated by measuring the change in temperature and mass of a substance during a phase change process.
