What is the difference between heat gain and heat loss?
These are exact opposities - heat gain is an increase in energy that results in an increased temperature of the material. Heat loss is a loss in energy that results in a decreased temperature of the material.
What is the reason for heat transfer from one substance to another?
Difference in temperature is the reason heat transfers from one substance to another.
Any movement of matter that results from differences in density?

How many pounds is 1050cc?
cc (cubic centimeters) is a unit of volume, not of mass. The results vary for different substances, depending on the density of the substance.cc (cubic centimeters) is a unit of volume, not of mass.

If you squeeze the foam you will increase its density why?
By squeezing the foam you are decreasing its volume, whereas its mass remains roughly the same. Therefor, as density is mass/volume, a decrease in volume results in and increase in density.
What is the effect of temp on density?
An increase in temperature results in a decrease in density.
How density is impacted by the temperature of the heat energy of the material?
An increase in temperature causes thermal expansion which increases the volume. This cause a decrease in density. Except in the case of water between 0 and 4 degrees C, where increased temperature results in a contraction and so increased density.

How deos this change in volume affect the density of solids liquids and gasses?
A change in volume with a constant, unchanging Pressure and Temperature results in increased or decreased density, inversely dependent on increase or decrease in volume.
If you have the same volume and the mass changes what happens to the density?
The density changes in direct proportion with the mass. A lesser mass results in a lesser density and a greater mass results in a greater density.
What are results in science?
The results are the data, information and conclusions you get at the end of an experiment. For example, if you were testing the density of various objects in water, your results would be the calculated density of each object.
What is the difference between observations and results?
the difference is that results are the answers to the observations.
What is the difference between sand replacement method and core cutter method to find out density?
Core cutter method is simple but results approximate and used on soft soils
Is a high salinity solution less dense than water?
No, increasing salinity results in higher density. This density increase means you will also be able to float more easily in more saline water. The higher the salinity the lower the temperature it will freeze.
How does the temperature of the medium affect the speed of the sound?
For most mediums, a higher temperature results in higher density, and sound travels through denser mediums faster than through less dense mediums, so a lower temperature generally increases the speed of sound waves.
What causes has pressure?
The answer depends on what kind of pressure. If you mean the pressure exerted by gasses on the walls of a container (a balloon, for example), pressure is created by the motion of the molecules of gas. Temperature and density of the molecules are factors. Higher density results in higher pressure. Higher temperature creates more molecular motion, thereby creating higher pressure.
Why density decreses with increse in temperature?
Density usually, though not always, decreases with an increase in temperature because as the substance heats up, the atoms gain more kinetic energy. The more energetic atoms can be thought of as bumping into one another more, causing the substance to expand. This expansion is especially apparent in gases, as the atoms in a gas have the greatest freedom of movement.One example of density increasing with an increase in temperature involves water, H2O. Water has the greatest density at 4oC, and thus raising the temperature of liquid water from 0oC to 4oC actually causes a small increase in density. This phenomenon results from the very open structure of maximally hydrogen-bonded water molecules.
