Chapter 3, Problem 56TQ
Summary Introduction
To review:
The reason for less density of ice than water, the effects on the oceans if the density of ice was not less than water, and the possible effects of high density of ice on the development of life on the earth.
Introduction:
It is unusual that water (H2O) has a maximum density in its liquid state (water) and not in its solid state (ice). Ice floats on water because it has less density than water. If its density would have been higher, then it would sink into the water and would affect aquatic life as well as the earth’s environment.

Question 4.3
Now it's your turn to design and experiment. Your Aunt Kayla and Uncle Jerome, want to be home-brewers. When they
find out that you have been studying yeast metabolism and the scientific method, they request your help in the study-
design portion. Uncle Jerome likes beer that is very carbonated; whereas Aunt Kayla likes beer that is only mildly
carbonated. They each want to make their own batch of beer. Using the information learned from this data, write
instructions for each person in terms of which carbohydrate source to use and how long to allow the incubation to occur.
Question 48 is based on the following passage.

f
The science of producing and transmitting sound
waves in materials has become widespread with
many practical applications. Ultrasonics was first
developed during World VWar II as a method of
detecting enemy submarines. Today ultrasonics
has many applications. When the waves used
are of a low amplitude, ultrasonics can be used
to map the ocean's depths, detect flaws in
materials, locate cancers in the human body,
and scan fetuses for deformities.
Higher-amplitude waves are used in cleaning,
manufacturing
fatigue tests for metals. The destruction of
bacteria
materials,
and
determining
and the use of tightly focused
ultrasound as a surgical knife are biological
applications of high-amplitude waves.

- Question 3 of 14 In 1910, Ernest Rutherford performed a set of experiments that helped scientists better understand the structure of atoms. He directed a beam of a particles (small, positively charged particles) at a very thin sheet of gold foil. He made several observations from the experiments. How did Rutherford interpret the fact that most of the a particles seemed to pass right through the foil? O Most of the volume of an atom is empty space so the a particles passed unobstructed through the electron clouds of the atoms. The foil was so thin that the a particles were able to pass in between the tiny, solid gold atoms. Gold is malleable so the gold atoms moved out of the way of the a particles and allowed them to pass through. How did Rutherford interpret the fact that a few of the a particles were deflected at very large angles? The a particles were striking the negatively charged electrons in the gold atoms. O The a particles were striking the neutrally charged neutrons in the…arrow_forwardQuestion 3 Describe the production of X-rays by a rotating anode tube.
