Because physical properties have a lot more resistance than chemical properties. Thickness is a physical property because it doesn't have reactivity. If I took a shoe and threw it at my friend, he would grow a bump on his head. That would be a physical property. The same thing applies here. A Feather is a chemical substance, and Iron is a physical substance. A Feather is more dense, and has less mass. Iron is less dense, and has more mass. The answer is simple: Different subsctances have different melting points and boiling points, therefore feather samples weigh more than iron samples.

Do people who weigh more have more blood volume?
People who weigh more do not normally have more blood volume. This is because what makes people overweight is fat not blood.
Why did Mendel study such a large sample of pea plants to determine the probability of inheritance?
The more samples you use, the closer your results will match probability.
When a researcher has two samples with two means one of the assumptions for two samples is independence of between the two samples What does this mean What happens if the independence assumption is?
Independence of the two samples means that the choosing of the first sample did not influence the choosing of the other sample, and vice versa. For example, if you were comparing running speed in two different brands of running shoes, you could look at two samples of people running a 100 m dash -- one sample of people running in Brand A and one sample of people running in Brand B. If those two groups were picked independently of one another, these samples would be independent. If, instead, you had the same group of people run the race twice (once in each brand of shoe), these samples would be dependent. Samples that are not independent are said to be "correlated", "interdependent", or "dependent". Because the two samples are correlated, you might get incorrect findings for your statistical study. For example, say you want to compare the heights of boys and girls. If you chose the samples by choosing a girl for the girl sample, then choosing her brother for the boy sample, your statistical analyses might be misleading if you didn't account for the fact that tall girls are more likely to have tall brothers, and short girls are more likely to have short brothers. By choosing siblings for the two groups, you have made the two samples not independent of one another. If the independence assumption is violated, you have to do a special type of statistical test. For example, instead of doing a two-sample t-test, you would have to do a paired t-test.
How much does a bushel of green pintoes weigh?
