What property of matter does gravity act upon?
Mass is the property of matter on which gravity act upon.
Why does a substance expand upon heating?
On heating any substance get more energy and due to that its bonds breaksing process starts. Most solids expand when heated, a familiar phenomenon with many practical implications. Among the rare exceptions to this rule, the compound zirconium tungstate stands out by virtue of the enormous temperature range over which it exhibits so-called "negative thermal expansion," contracting as it heats up and expanding as it cools, and because it does so uniformly in all directions.
Why is density considered an intrinsic property of matter?
Matter has got mass. Matter occupy space. The formula of density is mass upon volume. So matter has got density. So matter has to have density. That is why density is considered as intrinsic property of the matter.
Why is thermal expansion not visible in solids?
Thermal expansion in solids is normally very small - typically around one part in one hundred thousand for a one Kelvin temperature change. That means that a one metre long length of aluminium, for example, will only change size by 0.23mm when heated by 10kelvin - effectively invisible to the human eye. Thermal expansion, though can be visible to the unaided eye if the object is large enough - a kilometer long bridge, for example, may vary in length by as much as a metre or more between summer and winter, depending upon the seasonal temperature change, and will have expansion joints that allow sections of the bridge to expand into one another without changing the overall length of the bridge, and risking damage to the structure. If you were to look at these joints in winter and then in summer, you would see the difference that thermal expansion makes.
Is the force of gravity acting upon an object the object's mass?
No. Mass is a property of the object and doesn't change, no matter where the object goes or what's happening to it. The force of gravity on the object is its "weight" and that can change. It depends on, for example, what planet the object is on.

Does the independent variable really change independently of the other variable?
The relationship is a matter of cause and effect. An independent variable is given as one upon which another variable depends. So, for example, if you heat a metal pipe, the pipe expands. The amount of expansion is dependent upon the amount of heating that occurs, so expansion is the dependent variable, and the heating, which you may or may not control, is the independent variable. All it means is that if the independent variable ungoes a change, there is an associated and predictable change in the dependent variable. The two are linked inextricably, but one is cause, the other is effect, or to put it another way, you control the change in the dependent variable with input into the independent variable, but it doesn't normally work the other way around.
Does the coefficient of linear expansion depends upon length?
yes,according to relation coefficient of linear expansion depends upon original length.
Explain why the iodine test gave such results upon prolonged heating?
explain why the iodine test gave such results upon prolonged heating
Upon heating ice can melt and turn into a gas this is an example off?
The change of ice to a liquid is melting; the direct change of ice to a gas is sublimation.
Why a saturated solution on heating becomes unsaturated explain and give example?
On heating a saturated solution it becomes unsaturated because heating causes kinetic energy to increase the distance between the molecules of liquid. Thus the solute takes free space present in the solvent. That is why saturates solution becomes unsaturated upon heating.
Does lead carbonate decomposes upon heating?
Yes
Does mercuric oxide decompose on heating?
Mercuric oxide decomposes upon heating to give off mercury and oxygen.
What is created directly above water upon heating?
evaporation
What is the property of igniting in air upon heating?
The property is flammability.
