Use what you learned from the PhET Simulation on the Properties of Gases and from the 3.04 Gas Laws lab to answer the following question. Write a paragraph!
Scenario (not a real experiment): Start with a balloon at room temperature, measure the diameter.
Then put it into hot water and measure the diameter. Then put it into ice water and measure the
diameter
Explain why a balloon in hot water expands but a balloon in ice water shrinks. Be sure to
include the following information:
(1) the number of molecules
(2) the temperature
(3) energy of the molecules
(4) the pressure
(5) the volume

individual oxygen atoms are formed during photosynthesis.-c.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
