Divide each rock's mass by its volume. The rock with the higher number is denser. To find the volume, measure the rocks in a graduated cylinder, the one that displaces more water is denser.

If Two balloons a and b are filled with hot air and cold air respectively how would you compare their densities?
A<b
Can be used to compare the amount of radioactively labeled DNA in two or more samples?
Scintillation counter
How can you compare the density of two different minerals?
You can compare the density of two different minerals by measuring their mass and volume. The formula to calculate density is density = mass/volume. Once you have these measurements, you can compare the densities of the two minerals to determine which one is denser.
What is the difference between a chi-square and t-distribution?
Chi-square is a distribution used to analyze the standard deviation of two samples. A t-distribution on the other hand, is used to compare the means of two samples.
Describe two ways to compare the densities of unknown substances?
One way to compare densities of unknown substances is by measuring their mass and volume separately and calculating the density as mass divided by volume. Another method is to perform a displacement experiment where the unknown substances are placed in a known volume of liquid, and the volume displaced is measured to calculate the density.
You can roughly compare the of two mineral samples of the same size by hefting them?
Hefting is a simple method to roughly compare the weight of two mineral samples. By holding them in each hand, you can estimate which one is heavier based on the weight you feel. Keep in mind that this method is subjective and can only provide a general comparison, not precise measurements.
What two types of evidence geologist use to learn about earths interior?
Rock samples and Indirect evidence from seismic waves Direct evidence from rocks samples and indirect samples from seismic waves my science teacher told me
What can be used to compare the amount of radioactivity labeled DNA in two or more samples?
Scintillation counter
How do you tell if two samples are signficantly different?
Statistical tests like t-tests or ANOVA can be used to determine if two samples are significantly different. These tests compare means of the samples, account for sample size, and calculate a p-value to determine if the difference is significant. A p-value below a chosen significance level (commonly 0.05) indicates that the samples are significantly different.
How can you compare means of two samples when the samples are chi square distributed?
According to the Central Limit Theorem if the sample size is large enough then the means will tend towards a normal distribution regardless of the distribution of the actual sample.
What tool can be used to compare the mass of a large rock to the mass of two wooden blocks?
A balance scale can be used to compare the mass of a large rock to the mass of two wooden blocks. Place the rock on one side of the scale and the two blocks on the other side. By observing which side tips down, you can determine which has more mass.
Why did it take "risk takers" to bring jobs to southwest Detroit What did these risk takers do?
Federico has two samples of pure water—sample X and sample Y. Sample X has a volume of 1 L, and sample Y has a volume of 10 L. How do the boiling points of these two samples compare?
