through space is - (ANSWER)Physics
@#$%^

ions to form new minerals. Which physical science is BEST for studying these
processes? - (ANSWER)chemistry
6. (physical science) The science BEST for studying photosynthetic bacteria is -
(ANSWER)life science
7. (physical science) What is usually the main advantage of being able to do a
laboratory experiment rather than a field study if both investigations allow you to
collect similar information? - (ANSWER)It is possible to change only one variable at
a time.

that involves sending a space probe to a distant asteroid to land on it and collect
data? - (ANSWER)an observational study

10. (physical science) Which of these fields depends the MOST on observational
studies? - (ANSWER)earth science
11. (physical science) The kinetic theory of gases is based on the assumption that the
molecules that form the gas are in random motion and bounce off the walls of their @#$%^
container and off each other as if they were billiard balls. The forces between real &*()(*&
molecules are more complicated. - (ANSWER)Using a model ^%$
12. (physical science) Why can't astronomers carry out a scientific research study to
determine which visible star, other than our sun, is the nicest? - (ANSWER)There is
no way to prove any answer wrong.
13. (physical science) In 1811, physicist Amedo Avogadro proposed that the same
volume of two different gases at the same temperature and pressure contain the
same number of molecules. His proposal received little attention until the 1850s,
when chemist Stanislao Cannizzaro, in particular, argued that Avogadro's idea
agreed with all the physical and chemical laws discovered up to that time. Today,
Avogadro's statement about gases is sometimes referred to as "Avogadro's
hypothesis" or "Avogadro's law." Which statement describes when each of those two
terms would be MOST accurately applied? - (ANSWER)it is most accurately
described as a hypothesis starting in 1811, but a law after the 1850's
14. (physical science) Albert Einstein developed a detailed and far-reaching explanation
of gravity being caused by the bending of space and time by the presence of matter.
This explanation made far-reaching predictions of phenomena that were later
confirmed, such as the bending of the path of light when the path passed close by a
star. It is currently the basis for many phenomena observed in astronomy. Einstein's
explanation would be MOST accurately described as a - (ANSWER)theory
15. (physical science) Which of these describes a statement that has usually NOT yet
been tested? - (ANSWER)hypothesis
16. (physical science) Which of these is generally regarded by scientists to be the basis
for deciding issues in science? - (ANSWER)empirical evidence including
experiments and observation

17. (physical science) Which statement MOST accurately describes how our present
knowledge of the structure of atoms, as being composed of electrons, protons, and
neutrons, developed? - (ANSWER)Our understanding of atoms came piece by piece
from many different scientific researchers.

18. (physical science) The origin of water on Earth is not yet fully understood. To test one &*()(*&
of the hypotheses, scientists launched a gigantic observational balloon to the height ^%$
of almost 130,000 feet to measure the amounts of water in comets and asteroids
based on the light reflected from these objects. The science BEST SUITED to
calculating the forces required to launch the balloon to the required altitude is -
(ANSWER)physics
19. (physical science) The sun produces its energy by nuclear fusion reactions, in which
smaller nuclei are combined to produce larger nuclei. Forces responsible for the
nuclear fusion are called nuclear forces. The physical science that studies nuclear
forces is - (ANSWER)physics
20. (physical science) The observational balloon is filled with helium and vented to the
atmosphere. The height it reaches depends on the changes of the atmospheric
pressure during the day and night cycle. The science BEST for studying this daily
warming and cooling of the atmosphere is - (ANSWER)earth science
21. (physical science) Which physical science is the BEST to study the composition of
Earth's atmosphere? - (ANSWER)earth science
22. (physical science) When a candle burns, its molecules consisting of hydrogen and
carbon atoms combine with oxygen to produce carbon dioxide and water. The
physical science that is BEST for dealing with the changes of the paraffin into carbon
dioxide and water is - (ANSWER)chemistry
23. (physical science) Which physics topic would be the MOST important in chemistry?
- (ANSWER)how atoms bond to each other because of electric attraction of
oppositely charged electrons and nuclei
24. (physical science) Which of these terms BEST describes a research project in which
a big telescope is placed on a high mountain in Arizona to study the brightness
stability of the sun? - (ANSWER)an observational study
