What happens to the volume of a substance if it changes phase from a solid to a liquid?
it inreases cause it isn't a solid hard shape and so the liquid will fill its container like ice and water. ice is smaller but water has a larger volume
In what phrases of matter do substance have a fixed volume?
Solid & liquid.
What happens if density of a solid substance is more than liquid it is placed?
If the density of a solid substance is greater than that of the liquid it is placed in, the solid substance will sink to the bottom of the liquid. This occurs because objects with higher density will displace an equal volume of the lower density liquid, causing the solid to sink.
How does solidification affect an objects volume?
The volume of most substances will reduce if the substance changes from liquid to solid.
What happens if density of a solid substance is more than liquid?
If the density of a solid substance is more than that of a liquid, the solid substance will sink in the liquid. This is because objects with higher density will displace a volume of liquid that has a lower density, causing the solid to sink to the bottom.
What 2 characteristics are needed for a substance to be a solid?
A solid has a definite shape and volume A liquid has the shape of the container and a definite volume A gas has the shape and volume of the container so the two characteristics for the substance to be solid are: a definite shape a definite volume
When a substance changes from a liquid to solid it is...?
When a substance changes from liquid to solid is called freezing.
Does the volume of water change from solid to liquid form?
The water in ice has a larger volume that water in its liquid form. That is why Ice floats. Ice is less dense than liquid water.
How do shape and volume of a substance differ among its solid liquid and gas state?
Heat causes substances to change their state because, when heated, the molecules within the substance to move around faster. The faster the molecules bounce about, the weaker they are held together.
What is the point at which a substance changes from a solid to a liquid?
A substance changes from a solid to a liquid at its melting point
Is the density of gaseous substance likely to be larger or smaller then the density of liquid or solid substance at the same temperature and why?
Temperature in this instance will not affect density, but rather pressure. The density of the gas will be much smaller than the density of a liquid or solid of the same chemical because it is a gas. The formula for density is mass over volume, and a gas has no measurable mass, making the gas always less dense than the liquid and the solid.
What physical characteristic is the same for the liquid and solid states?
Both gases and liquids can assume any shape for a given volume and pressure.
