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?
1. using a model
2. formulating a hypothesis
3. carrying out an observational study
4. performing a field study
1. 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?
, 1. Existing telescopes aren't powerful enough.
2. There is no way to prove any answer wrong.
3. The Hubble telescope has better uses.
4. A project of that sort cannot get funding.
2. 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?
1. It is most accurately described as a law throughout.
2. It is most accurately described as a hypothesis throughout.
3. It is most accurately described as a hypothesis starting in 1811, but a law after the
1850's.
4. It is most accurately described as a law starting in 1811, but a hypothesis after the
1850's.
3. 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?
1. hypothesis
2. theory
3. law
4. fact
2. theory
