A solid or liquid would not change in density because the volume would not change. The density of a gas would increase when cooled and decrease when heated provided the volume is allowed to change as a function of temperature. However, density of a gas is generally not measured because it is not a useful metric to use.

That is a rubbish answer.
Almost all solids or liquids expand when heated. (Pure water under "normal" circumstances has an anomalous phase between 0 and 4 deg C). So heating will increase the volume thereby decrease the density.

What are the properties of thermometric material?
when objects are heated or cooled, their temperatures change, along with some of their properties, these properties are known as Thermometric Properties. Examples include: when objects are heated, they expand, when they are cooled, they shrink. Another is, if an object is heated, its' gaseos pressure will increase and will decrease when object is cooled.Read more: What_are_thermometric_properties
Why does metal become more brittle after being heated then cooled?
Not all metals do, and it depends on the rate at which the metal is cooled. Basically, in some metals the crystal pattern in the metal changes when heated- and if rapidly cooled, that pattern is sort of "locked in" to the metal. If that locked in pattern is harder or more brittle than the earlier state, the metal has become more brittle. However, heating and then SLOW cooling can make some metals less brittle- it is called annealing.
What are some characteristics for a physical change?
A physical change is a change that can be reversed easily and no new substances are made. Examples are state changes ie. solid to liquid or liquid to gas.
Why can't some substances not go through chemical changes easily?
They are near to saturate state so they cant change easily
If an ice cube is placed in a pot that is heated what will happen after it has melted is it a chemical or physical change?
When ice melts and becomes a liquid it is a physical change. When the liquid boils and becomes gaseous it is a physical change. It is a chemical change when the molecular structure has been changed in some way, here it has not.
Why wouldn't the temperature of a substance change when heated or cooled?
There are two points for most substances where a phase change takes place. The energy used to rearrange molecules, called the heat of entropy, must be added or removed before the phase can change. The substances show little or no temperature change at some point in this process.
Do metals expand when they are cooled?
No, most substances contract with cooling, only some exotic substances (eg water) expands when cooled.

Can a liquid be changed?
Yes. You can dissolve substances in it to alter its physical composition, it can be heated to a vapour form or cooled to a solid (usually), or it may react chemically with other substances,Yes, in many ways. Here is a list of some ways:Liquids can be heated until they become vapours. Most liquids can be cooled until they solidify.You can add solutes or other liquids to make solutions, homogeneous mixtures or emulsions.Some liquids will react chemically with substances to create different chemical substances.Liquids can be decomposed into some chemical components by electrolysis.
Is white powder an element when it is heated?
The temperature of a substance does not change whether it is an element or a compound, though some substances will react when heated. White powder is not any particular substance. There are many substances that can come in the form of a white powders, but the only one that is an element is phosphorus. All the rest are compounds, though some of those may break down into their base elements when heated.
Do most solids expand when cooled?
Generally speaking, substances have the least amount of surface area as a solid, as they are heated they form a liquid and expand, as this is heated it forms a gas and expands more. *Assuming pressure is constant **Water is the only substance to expand as it freezes
Are all substances the same before and after burning?
No, some substances change their whole form and others just change their color and shape.

When a substance is heated its temperature increases. What other change might be observed?
Ordinarily when a substance is heated it expands. In some cases it melts. In some cases it vaporizes/evaporates.
Can elements be split up into simpler substances by heating them?
While some compounds do degenerate to their elements when heated, almost none do.
How do some objects change when they are heated?
Solid objects may melt into a liquid form when they are heated. Liquids may become gases when heated. When objects are combined and heated, they can become new objects altogether, like in cooking.
Why do some plant materials change color in the presence of acidic or basic substances?
This is how they react to the substances. Sometimes the substances that are inside the plant will react in an unusual way with the substance.
