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.

When a liquid is addedthe mass becomes 163g. What is the mass of the liquid?
To determine the mass of the liquid, you need to know the initial mass of the container or the substance before the liquid was added. If the initial mass is not provided, you cannot calculate the mass of the liquid accurately. However, if you have the initial mass, simply subtract it from the final mass of 163g to find the mass of the liquid.
How is the mass of a gaseous substance affected after it condenses?
The mass remain unchanged, only the density is variable.
How do temperature and pressure affect the rates of mass transfer in gassesliquids and solids?
the rate of mass thrnsfer can be affected higher in gases, slower in liquid and it is not affected in solid
Does the mass change when something goes from solid to a liquid?
No, the mass of a substance remains constant when it changes from a solid to a liquid. The particles are simply rearranging from a fixed pattern in a solid to a more fluid arrangement in a liquid, but the total number of particles remains the same.
Why ethanol with molar mass of 46gmol boils at 78 degree Celsius than water with molar mass og 18gmol boils at 100 degree Celsius?
The boiling point of a substance depends on intermolecular forces. Ethanol has stronger intermolecular forces (hydrogen bonding) compared to water. This leads to a higher boiling point for ethanol despite its lower molar mass.
The boiling point of a substance is affected by what?
the mass of the substance Well, the mass of the molecules of the substance. The amount of materail does not affect the boiling point. However, the forces between the molecules does affect how much energy is needed to change the liquid to vapor. Heavier molecules have higher forces. Polar molecules have higher forces, but not as high as charged ions. Also, the atmospheric pressure on the liquid affects the boiling point. Higher pressure helps keep the liquid in the liquid state. Lower pressure makes it easier for the vapor to break out. Water boils at a lower temperature in the mountains than it does on the sea shore. That's why there are special directions for baking cakes at high altitude.
How is the mass of a substance affected by physical changes like breaking apart?
no change in mass
How is Stoichiometry use to calculate energy absorbed when a mass of liquid boils?
Grams liquid × mol/g × Hvap

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.
How is the mass of a gaseous substance affected after it condenses?
The mass remain unchanged, only the density is variable.
Does a substance loose mass when changing state?
It depends. Exapmle: If a solid changes into a liquid, it looses mass. If a liquid changes into a solid, it gains mass. I think...
What happens to the mass of water in a tea kettle when it boils?
The liquid mass is partly converted to a gas (steam, water vapor), so if this escapes, the mass is no longer there. The steam can, however, be captured and condensed, and used again (as in steam engines).
How do temperature and pressure affect the rates of mass transfer in gassesliquids and solids?
the rate of mass thrnsfer can be affected higher in gases, slower in liquid and it is not affected in solid
What is the mass of one milliliter?
A milliliter is a unit that is used to measure liquid volume. The mass of one milliliter of a substance would vary greatly depending on the substance.
Does the mass change when something goes from solid to a liquid?
No, the mass of a substance remains constant when it changes from a solid to a liquid. The particles are simply rearranging from a fixed pattern in a solid to a more fluid arrangement in a liquid, but the total number of particles remains the same.
What density of liquid has a mass of 95?
The density of a liquid with a mass of 95 grams depends on its volume. Density is calculated by dividing the mass of a substance by its volume. So, without knowing the volume of the liquid, we cannot determine its density with just the mass provided.
