Question

Please, can somebody help me with this project? I'll give brainlest for the best answer! (Do not answer if you don't know or only want points.)
Online Lab:
This animation will allow you to find the density of a penny, a nickel, and a quarter.

Make a hypothesis in which you suggest which coin will have the highest density and which will have the lowest density. A model hypothesis might be: "If the (fill in the name of a coin) has a greater density than the _____ and _____, then it will have a greater mass to volume ratio. If the (fill in the name of a coin) has a lower density than the _____ and _____, then it will have a lower mass-to-volume ratio.

Data sheet:
Hypothesis:
Mass of 5 pennies
Mass of 1 penny
Mass of 5 nickels
Mass of 1 nickel
Mass of 5 quarters
Mass of 1 quarter
Volume of 20 pennies
Volume of 1 penny
Volume of 20 nickels
Volume 20 quarters
Volume of 1 quarter
Density of a penny
Density of a nickel
Density of a Quarter

Write one or two summary paragraphs discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph.

According to your data, was your hypothesis correct? (Be sure to refer to your data when answering this question.)
Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
List at least two real-world examples that apply the findings of this experiment. (Hint: An example of this type was given in the introduction to this project.)

Answer 1

The density of the nickel was greater than that of the quarter and penny, thus, the results supports the hypothesis.

What is density of substance?

The density of a substance is a measure of how tightly-packed the particles of the substance are.

Density is calculated as the ratio of the mass of the substance and the volume of the substance.

• Density = mass/volume

The hypothesis of the lab to compare the densities of a penny, a nickel, and a quarter is:

• If the nickel has a greater density than the quarter and penny, then it will have a greater mass to volume ratio. If the nickel has a lower density than the quarter and penny, then it will have a lower mass-to-volume ratio.

The average mass and the average volume of a penny, a nickel, and a quarter are then used to determine the density of each coin.

Based on obtained results, it would be found that the density of the nickel was greater than that of the quarter and penny. Therefore, the results supports the hypothesis.

In conclusion, the density of a substance depends on the mass and the volume.
