which has more volume? a kg of gold or a kg of aluminum? please explain in physics terms
Think of it this way: Which metal is lighter? How do you know this? Because a given volume of gold weighs more than a given volume of aluminum. So which one has more volume? A kg of aluminum.
Aluminum The density of Aluminum is pretty low. Gold has a very high density, almost twice as dense as iron. Density = mass / volume
Gold is a heavy metal and aluminum is very light. So aluminum would take up lots more space than an equal weight of gold, even if the aluminum was forged into a smaller size.
Aluminum. Since it's less dense than gold, you need more aluminum to get a kg. Density = mass/volume. Density of gold density of aluminum
The density of gold is higher than the density of aluminum, so a kg of gold would take up less space than a kg of aluminum. But to answer your homework, you should look up the specific gravities of each of these metals, and figure out the volume of a kg of each....
