Why will a crumpled ball of aluminum sink in water?
A crumpled ball of aluminum will sink in water because it is denser than water. Even though aluminum can float in its solid form due to its low density, once crumpled into a small, dense ball, its overall density increases, causing it to sink.
Which weighs more a sheet of aluminum foil or the same sheet crumpled into a tight wad?
I see no reason why the weight should change if you crumple it.
What two things affect density?
The two main factors that affect density are the mass of an object and its volume. An increase in mass or a decrease in volume will lead to an increase in density, whereas a decrease in mass or an increase in volume will result in a decrease in density.
Does the surface energy increase or decrease with increase in planar density?
The surface energy decreases with an increase in planar density. This is because a higher planar density means more atoms are closely packed together, leading to a decrease in the number of surface atoms and therefore a decrease in surface energy.
If the pressure in a fluid is affected what characteristic of that fluid?
If the pressure in a fluid is changed, its density is typically affected. In general, an increase in pressure leads to an increase in density, while a decrease in pressure results in a decrease in density.

What happens to the density of aluminum if you heat it?
When you heat aluminum, its density decreases. This is because the atoms in the metal vibrate faster and more energetically, which causes them to spread apart slightly. The increase in volume with temperature causes a corresponding decrease in density.

What effects of increase does density do?
Density decrease when the temperature is raising.
Does evaporation of salt water cause it to increase or decrease density?
The density increase after evaporation.
How does a change volume affect an objects density when mass stays the same?
With constant mass, a decrease in volume will increase the the density. Conversely, an increase in volume will decrease the density.
Do evaporation of salt water cause density to increase or decrease?
The density of water increase after evaporation.
Do evaporation of salt water cause density increase or decrease?
During evaporation the density increase.
What is the effect of temp on density?
An increase in temperature results in a decrease in density.
When the air rises does it increase or decrease?
When air rises, it expands and cools, which causes its density to decrease. Conversely, when air descends, it compresses and warms, which causes its density to increase.
Does the surface energy increase or decrease with increase in planar density?
The surface energy decreases with an increase in planar density. This is because a higher planar density means more atoms are closely packed together, leading to a decrease in the number of surface atoms and therefore a decrease in surface energy.
