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 how the light from the candle travels through space is
Physics
Auroras are bursts of light that happen when charged particles from the sun interact
with Earth's magnetic field and atoms and molecules in our atmosphere.
Physics
The physical science that is BEST for finding the best locations to drill for the
petroleum used to make the candles is
Earth Science
The science BEST for studying how hydrogen sulfide and carbon dioxide react is
Chemistry
Acidic soil reacts with common rock-forming minerals to release ions to form new
minerals. Which physical science is BEST for studying these processes?
,chemistry
The science BEST for studying photosynthetic bacteria is
Life Sciece
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?
It is possible to change only one variable at a time.
Which of the following terms best describes a research project that involves sending a
space probe to a distant asteroid to land on it and collect data?
an observational study
A space probe is an unmanned spacecraft. Which of these terms BEST describes a
research project in which a space probe is sent to collect soil samples on planet Mars
and then report the data back to Earth?
a field study
Which of these fields depends the MOST on observational studies?
Earth 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. This is an example of
Using a model
Why can't astronomers carry out a scientific research study to determine which visible
star, other than our sun, is the nicest?
There is no way to prove any answer wrong.
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?
It is most accurately described as a hypothesis starting in 1811, but a law after the
1850's.
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
theory
Which of these describes a statement that has usually NOT yet been tested?
hypothesis
Which of these is generally regarded by scientists to be the basis for deciding issues in
science?
empirical evidence including experiments and observations
Which statement MOST accurately describes how our present knowledge of the
structure of atoms, as being composed of electrons, protons, and neutrons,
developed?
Our understanding of atoms came piece by piece from many different scientific
researchers.
Why is it important to have standard measures for physical quantities?
To allow for the comparison of measurements with anyone familiar with the
measurement system.
