8. 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.
Working conditions are always better indoors.
The measuring equipment will be more precise.

12. 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
formulating a hypothesis
carrying out an observational study
performing a field study

Existing telescopes aren’t powerful enough.
There is no way to prove any answer wrong.
The Hubble telescope has better uses.
A project of that sort cannot get funding.

14. 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 law throughout.
It is most accurately described as a hypothesis throughout.
It is most accurately described as a hypothesis starting in 1811, but a law after the
1850’s.

15. 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
hypothesis
