For most substances over all temperatures as you heat a substance it will become less dense and as you cool it the substance will become less dense. But as with any law there exceptions. Liquid sulphur for example will become less dense as it is heated up to a certain point and then as you continue to heat it the sulphur becomes more dense. But the most noteable exception is water. As water cools from a vapour to a liquid and is then further cooled as a liquid it becomes more and more dense until it reaches 2 degrees C. Then as water cools below this point it becomes less and less dense until it starts to solidify. At this point it becomes less dense. Water is one of very few substances whose density as a solid is less than when it is in a liquid state. It is a good thing to or we would never have invented hockey if the ice had been on the bottom of the pond.

Does a change in the mass affect the density of the object?
Adding mass may increase or decrease the density if the substance added is different. Merely changing the mass will not affect the density.
Does the material of a balloon affect its expansion rate heating or cooling the balloon?
Yes of course everything depends on what the balloon is made of.
How does volume affect specific gravity?
Specific gravity is otherwise known to be "Relative Density". It is the ratio of the density of a substance to that of water as water has been taken as standard. So though volume gets changed there is no chance to get change in the relative density as it is the characteristic property of the substance.
Does size can affect floating and sinking?
To determine if an object will float in a substance, you look only at its density
How does heating air affect its density and presure?
Hot air is less dense than cold air. Heating a sealed, rigid container of air will increase the pressure of the air in the container.
How how do the heating and cooling differences between land and water affect people on earth?
How do the heating and cooling differences between land and water affect us? ...
What will affect the density of a substance?
Density=mass/volume
How do mountains and bodies of water affect patterns of heating and cooling?
Your question can be rephrased as two linked question. "How does climate affect patterns of heating and cooling?" and "How do mountains and bodies of water affect climate?" The answer to the first should be obvious to you. The second is not really an HVAC question.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
Why does mass or volume affect the density of a substance?
Because density is DEFINED as mass/volume.
Could food colouring added to the substance affect the density calculation of the substance?
no it could not
Does a change in the mass affect the density of the object?
Adding mass may increase or decrease the density if the substance added is different. Merely changing the mass will not affect the density.
If a given substance is cut into a different shap the object affect its density why?
It acually doesn't affect it's density, only the mass changes.
How does substance's density affect its boiling point?
A relation between the boiling point and density doesn't exist.
Which classification of property does not affect density?
Density is mass divided by volume. Density is an intensive property which means that increasing the amount of the substance does not increase its density.
Does shape affect density?
The shape of a substance does not affect density of a substance. The density is a physical Quantity which is predefined and constant for each substance. By the equation Density=mass/volume It is clear that the density is affected by mass & volume of the substance and not the shape. However the shape of a substance affects the area acquired by the substance. Like every natural body is spherical in shape like river stones,asteroids,planets,raindrops,dewdrops because they try to acquire the minimum possible area and sphere is the only geometrical figure occupying minimal area.
Why does mass and volume affect density?
The density of a substance is its mass divided by its volume. So for the same volume the higher the mass, the higher the density.
