Why is it important to say the state of a substance with its temperature?

This is due to the fact that solubility is affected by temperature. In general, more solute can dissolve in a solvent at higher temperatures.

How does the temperature of a substance change as it gains or loses heat?
A substance (in this case water) that gains or loses 'sensible' heat will change it's temperature at the rate of 1 deg F per pound of that substance per 1 btu loss or gain.That is to say that 1 pound of water will change 1 deg f as it loses or gains 1 btu of heat energy. That heat required to lose or gain 1 deg f is referred to as sensible heat, whether lost or gained, since it does change the temperature of the substance.However, that substance must gain or lose latent heat during a change of state; as in water changing from liquid to gas (steam). Latent heat affects the substance during it's change of state, and does not change the temperature of the substance during that change of state.Each substance has a specific heat, and so each substance has a different value of btu's required to make a change in their state or temperature.
What physical property can not identify a substance?
state of matter for example,you cannot say a liquid is water because it is liquid,so state of the substance is a physical property that is very uncertain in deducing what the substance is.
Is a hydrate a pure substance or a mixture?
i say pure substance
When can you say that a substance is homogeneous?
when can we say that a subtance is homogenous
Why you say that a paper or matchstick as a combustible substance?
Anything that can burn is a combustible substance.

What happen to volume of substance when placed say in a freezer?
A number of factors have to be considered, the state of the substance, solid, gas or liquid. The condensation and freezing point of the substance. The temperature inside the freezer. The pressure Most, but not all, substances reduce in volume and increase in density when cooled. Water for instance, reduces in density when frozen.
The temperature at which a given substance will change from a liquid into a gas?
The temperature in which a given substance will change from a liquid to a gas is its boiling point. Every element, compound and mixture has a different boiling point. Use an SI data book or the internet to find the boiling point of a particular suubstance.
Which substance will sublime at room temperature?
CO2(s) and I2(s) Carbon dioxide as a solid and iodine crystals as solids. These are the two most important sublimation compounds! When I say sublimation, you say CARBON DIOXIDE AND IODINE! :)
Why do you say a substance in a liquid phase is more disordered than the same substance in a solid phase?
In a solid state, the molecules are less free to move around. They are in an order, all bunched together neatly jiggling in their space. In a liquid state however, the molecules are more free to move around, they can be adjusted and moved easily. Since the molecules can move more freely in a liquid state than a solid state, there is more disorder in the liquid state than in the solid state. This goes up the chain of states of matter by the way, from solid to liquid to gas to plasma, the disorder increases as the substance temperature increases.
How does a substance's boiling point or melting point determine its state at room temperature?
If its still a solid at room temperature then to melt it would have to be at a higher temperature than 20 degrees. If its still a solid at room temperature then to melt it would have to be at a higher temperature than 20 degrees.
When oxygen is added to a substance you say that it is?
When oxygen reacts with a substance we say the substance has been oxydized.
Is oxygen not ductile?
The term doesn't apply in this case. You can only say whether a substance is ductile if it is a solid. Oxygen is a gas at room temperature.

What substance is most likely to exist as a crystalline solid at room temperature HI N2 NF3 KCl SO2?
I would have to say KCl.
