AWS Community Day CPH - Three problems of Terraform
Ppchemistry
1.
2. includes the thermal
expansion of gases, how vapors
operate at different
temperatures and may expand
or change pressure, and what
applications these results could
have.
3. could be converted to water, or H2O, when
combined with oxygen.
Lavoisier thus gave these elements the names
oxygen and hydrogen, which are still used to this day.
4. when mass is able to change either its shape or
form, the mass will remain the same no matter what.
He also was responsible for writing the first
official list of elements, which he termed the
"Elements of Chemistry." This was then adapted over
the years to become the Periodic Table of Elements
that is taught to chemistry students from a very young
age.
5. English chemist and physicist
gave an estimate of the density of the Earth.
In 1798, Henry Cavendish published his estimate
of the earth's density, which is now almost exactly
what modern scientists have also deemed it to be. In
many ways, he is now considered to be almost a
century ahead of his time.
6. the periodic table by placing the elements in
order of increasing atomic weight (1869), Predicted
the existence and properties of elements that would
fill the gaps left in his chart (1871), These elements
were discovered between 1875 and 1885
7. inversely proportional
relationship between the pressure
and volume of a gas, as long as the
gas is kept at a stable
temperature.
In basic terms, if the pressure goes up, then the
volume will go down.
8. The formula for this law is:
P1V1 = P2V2
whereas, P1 is the original or starting pressure, P2 is
the final pressure, V1 is the starting volume and V2 is
the final volume.
9. a substance that could
make the dye stick to
cotton. This discovery led
to our present day
synthetic dye industry.
10. This law states that if there
are equal volumes of gas existing
under equal temperatures and
pressure conditions, the gas
volumes will then contain
correspondingly equal numbers
of molecules.
11. formed a new method of classification for this
radiation, including alpha, beta, and gamma rays.
12. first chemist to prove that
oxygen was essential to combustion.
Priestley named the gas "dephlogisticated
air", later renamed oxygen by Antoine Lavoisier.
Joseph Priestley also discovered hydrochloric
acid, nitrous oxide (laughing gas), carbon
monoxide, and sulfur dioxide.
