What else can I help you with?
The density of water is equal to 1.0gcm3. a substance with density equal to cm would be what in water?
If a substance has a density of 1.0 g/cm3, it would have the same density as water. This means that the substance would neither sink nor float in water, as it would be neutrally buoyant.
Is Dry ice a pure substance?
there is a phase change that is water(liquid) is converted into ice now the question arrives that it is a pure substance or not? if its chemical composition is the same during the phase change then it is a pure substance otherwise not.
Are water and moisture the same thing?
Water refers to the chemical compound H2O, while moisture is a general term indicating the presence of water in any form in the air or a substance. While water is a specific substance, moisture can refer to water vapor or liquid water depending on the context.
How are solids liquids and gases the same?
Most common sustsances, compounds or elements can occur in all the three states of matter: gas, liquid and solid. For example, water as a solid is called ice. As a liquid, it is called water. As a gas, it is called steam or water vapor. The answer is: liquid, solid and gas can be the different states of an element, a compound, or substance, or they can be same .
If a liquid with large particles is shaken until all particles are dissolved what is the new substance?
There is no new substance; it is just mixed up and all the atoms are spread out so you can't see the individual particles.
If 1 liter of substance weighed 1 kilogram what would the substance be?
A substance with approximately the same density as water.
Are water and ice the same substance or different substances?
Water and ice are the same chemical substance in different physical phases, liquid and solid respectively.
Is ice in a glass of water a substance or mixture?
if you are comparing the water and Ice then it is neither. they are both the same.From one point of view you have a mixture - even though they are the same - one is in the solid state and the other is in the fluid state.From another - its an homogeneous substance since they are the same element.To be literal as to your question: which is about the ICE itself and the water is not actually the substance in question. With that then the Ice is a substance and as long as it is ICE is is not mixing with the water. When the state changes from solid to liquid the melted liquid has become the other substance and is no longer ICE.
Is liquid water a water vapor?
No: Vapor is defined as the gas phase of a substance that is mostly solid or liquid at equilibrium at standard temperature and pressure. Therefore, a liquid itself is never a vapor, but the liquid is in equilibrium with a vapor phase that contains the same chemical substance.
What are the observable changes in freezing water?
liquid to solid
Is water a non-uniform example?
No, water is a uniform substance because it has the same chemical composition and properties throughout when in its liquid form.
How can ice water and steam be three states of a substance and not different substances?
Well you can prove they are the same substance by experimenting. If you boil liquid water it turns into steam and if you then cool the steam, it turns back into liquid water. If you cool liquid water it will freeze and turn into ice and then if you warm the ice it will melt and tun back into liquid water. Thus the common substance in all three states is the water. ------------------------------------------------------------- In general substance are either solid, liquid or gaseous at normal temperatures and pressures and if you heat the solids they will turn into liquid then gas and if you cool the gases they will tun into liquid and then solids. Solid, liquid and gas are 3 of the possible states of matter (there are other states possible)
Are the melting point of solid and freezing point of liquid of a substance different?
yes the melting point of solid and freezing point of liquid of a substance is differ but in the case of water the melting and freezing point is same.
Is ice to water a new substance?
No. Its called water. Ice is water, water is water, water vapor is water; all are in different states of the same compound.
The density of water is equal to 1.0gcm3. a substance with density equal to cm would be what in water?
If a substance has a density of 1.0 g/cm3, it would have the same density as water. This means that the substance would neither sink nor float in water, as it would be neutrally buoyant.
Are the melting and freezing of a substance the same?
Yes. A substance melts and freezes at the same temperature. Melting is as it changes from solid to liquid, freezing is from liquid to solid.
Is water the same thing as gas?
Yes
