Suppose you have two cubic meters of uranium, four cubic meters of lead, four cubic meters of copper. Rank them by mass, from smallest to largest.
a)lead, copper, uranium
b)uranium, copper, lead
c)copper, uranium, lead
d)uranium, lead, copper
can someone help me
please look up the density of each.
copper
lead
uranium
then multiply by volume
copper mass = copper density * 4
lead mass = lead density * 4
uranium mass = uranium density* 2
then list them in order
To rank the given substances by mass, we need to know their respective densities. However, assuming that the density of uranium is greater than lead and the density of lead is greater than copper, we can make an informed estimation:
Given that you have two cubic meters of uranium, four cubic meters of lead, and four cubic meters of copper, we can estimate the ranking by mass as follows:
1) The substance with the least mass is copper, so it should be ranked first.
2) Lead is denser than copper, so it should be ranked second.
3) Uranium is denser than both lead and copper, so it should be ranked third.
Based on these estimations, the correct ranking from smallest to largest mass would be:
c) copper, uranium, lead
Certainly! To rank the three materials by mass, we need to compare their densities. Density is defined as mass divided by volume.
To calculate density, we need to know the mass and volume of each material. However, you've only provided the volume of each material, not the mass.
To proceed, we will need to assume that all the materials have the same density throughout their entire volume. This assumption may not be accurate in reality, but for the purpose of this exercise, we will proceed with it.
Given this assumption, we can now compare the volumes to rank the materials.
The cubic meter is a unit of volume. To compare volumes, we can simply compare the numerical values you provided.
You have two cubic meters of uranium, four cubic meters of lead, and four cubic meters of copper.
Comparing these volumes, we can determine the ranking:
- Uranium (2 cubic meters)
- Lead (4 cubic meters)
- Copper (4 cubic meters)
So, based on the provided volumes, the correct ranking from smallest to largest mass is:
d) Uranium, lead, copper
