Mass does not change during a chemical change how about for a physical change?
Physical changes are like cutting paper. The mass does not change. Chemical changes do not change total mass either. If you put a candle in a sealed container so that you may measure the total mass of the candle and the air before burning, then light the candle electrically but keep everything sealed, the total mass after burning will still be the same. But if you measure only the candle, then its mass has changed. So the mass of one single 'ingredient' will change during a chemical change.
A characteristic of matter that is exhibited without a change in identity?
the volume or mass of the matter. it can change states such as solid liquid or gas, which would be deemed to be the same chemical identity, but a different state of matter
Change of a liquid to a gas?
The change of a liquid to a gas is Vaporization. Not to be confused with "Evaporation".
How does volume and mass affect density?
Density = Mass/VolumeHigher Density = higher mass, lower volume.Higher mass means a higher density.Higher volume means a lower density.Of course, this is mathematically speaking. Changing Mass in a realistic experiment is unlikely...and a volume change is usually only via a change of state. But those are the relationships.
When you heat 0.80g of copper carbonate and you weigh it after cooling how come the mass didn't change?
Heating copper carbonate (CuCO3) should result in the generation of copper oxide (CuO) and carbon dioxide gas (CO2). Therefore, the weight (mass) of the material remaining should decrease by an amount equal to the mass of CO2 lost. If the mass didn't change, you didn't heat the copper carbonate sufficiently to cause the decomposition.
Does a hot gas have ore mass than the some gas when it is cold?
No. Heat doesn't change the mass of a gas.
Will changing the volume of a container filled with gas change the mass of the gas?
No, changing the volume of a container filled with gas will not change the mass of the gas. The mass of the gas remains constant unless gas is added or removed from the container. Changes in volume only affect the pressure and density of the gas.
When a gas is heated its mass?
The TOTAL mass of the sample stays the same, but keep in mind that you can only measure it accurately if you can keep the sample confined, which can be difficult when changing a liquid to a gas. When heating a gas, it usually expands (or increases pressure in a rigid container).
Does a gas have mass and volume and state?
Yes, a gas has mass because its molecules have mass. A gas also has volume, although this volume can change based on the conditions it is in. A gas can exist in different states (solid, liquid, gas) depending on its temperature and pressure.
How much mass will the gas have if 100 grams of water evaporate into a gas?
Matter might look different after a physical change, but the kind of matter itself does not change. Its particles have not changed. They are just packed together differently.
What are two ways mass can change?
Mass can change by adding or removing material from an object. This can either increase or decrease the mass of the object. Additionally, mass can change through physical or chemical reactions where the composition of the object is altered.
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.
Is a change in mass an indicator of chemical reaction?
A change in mass can be an indicator of a chemical reaction if there is a conversion of reactants into products with different mass compositions. For example, if gas is released during a reaction or if there is a change in the number of moles of substances present, there may be a noticeable change in mass.
What happens to the mass of gas when temperature is decreased by -273 degree celsius?
The Mass of a substance will not change with a reduction of temperature … even to -273C.
Does gas have definite mass?
Yes, gas has mass. The mass of a gas is determined by the number of gas particles present and the type of gas molecules. The mass of gas can be measured using a balance or by determining the mass of the container before and after the gas is added.
Does an object changes its mass when it changes to gas?
Actually no, the only thing that changes is the density. The mass doesn't change when it's changing states.
How is the mass of an object affected when the object changes state?
The mass of an object remains the same when it changes state, such as from solid to liquid or gas. Mass is a measure of the amount of matter in an object, and this does not change during a change in state.
