Does the mass change when something goes from solid to a liquid?
No, solids do NOT change mass when they change form into a liquid. The only way the mass can be changed is if the substance goes from a liquid to a vapor or gaseous form.
What does the lantent heat of vaporization measure?
the amount of heat required to change the state from liquid to vapour of unit mass without changing the temperature
Why is it that when a solid dissolves in a liquid the mass of the solution that is made is the same as the mass of the solid added to the liquid?
this is because the amount of solute in the solution will have the same number of moles as that of the solid.
When you cool a liquid will it become lighter?
Apart from insignificant effects due to the Special Theory of Relativity (less energy implies less mass), there will be no change in the mass, and therefore no change in the weight. The density of a liquid, however, will change, since the volume changes.
What are the factors which determine a chemical change?
Change in colour, mass and state(ie liquid, gas or solid)
What is the difference in mass between a solid and a liquid?
A solid and liquid have the same mass if the amount is the same.
Does the mass change when something goes from solid to a liquid?
No, solids do NOT change mass when they change form into a liquid. The only way the mass can be changed is if the substance goes from a liquid to a vapor or gaseous form.
The heat of fusion is defined as the energy required at constant temperature to change 1 unit mass of a?
The heat of fusion is the amount of energy required to change 1 unit mass of a solid to a liquid at constant temperature.
What does the lantent heat of vaporization measure?
the amount of heat required to change the state from liquid to vapour of unit mass without changing the temperature
When a given quantity of a liquid is heated the mass quantity will vary and how?
The volume will increase, since most liquids tend to expand when they are heated. The mass will NOT increase, for most practical purposes - since there is something called "conservation of mass". However, the energy added to the liquid is equivalent to a small amount of mass; this is insignificant for most practical purposes.
What happen when a liquid change to a gas?
precipation
What affects the amount of solid a liquid will hold?
A soild as more mass
How are a liquid's mass and volume different?
The mass of any substance measures the amount of 'stuff', and is usually determined by weighing it. The units are often kilograms. The volume is the space it takes up. Volume is measured in units such as metres cubed or litres. The mass of a liquid will be related to the volume via the density. Mass = [volume] x [density] You can change the volume without changing the mass by changing the temperature of the liquid; liquids generally become more dense as they get colder and less dense as they get warmer.
Does the mass of a substance change after a chemical reaction changes the substance from a liquid to a solid?
No. According the the law of conservation of Mass, it would be physically impossible for the mass of the substance to change. However, it is possible for the volume (amount of space taken up by the substance) to change, as well as it's weight (if gasses are released or molecules in the air are involved).
What happens to the mass when a gas or liquid is heated?
The amount of mass does not change. The energy contained by the fixed mass increases.
How does gas change into liquid water?
gas is turned into a heaver mass and there for turns into a liquid.;P
Is the concentration of a liquid dissolved in a liquid expressed as a percentage by mass?
You would express as the amount of solute over solvent.
