Question | Answer |
---|---|
P1V1 = P2V2 | Boyle's Law |
this can be used to determine if a substance is an acid or base | litmus paper |
V1/ T1 = V2/ T2 | Charles's Law |
P1/ T1 = P2/ T2 | Gay Lussac's Law |
the relationship between variables in Boyle's law | inversely proportional |
the relationship between variables in Charles and Gay-Lussac's laws | directly proportional |
time it takes a radioactive isotope to decay by 50% | half life |
creating energy through the splitting of heavy unstable nuclei into lighter nuclei | nuclear fission |
a measure of how much the volume of matter decreases under pressure (when squeezed) | compression |
the constant in Boyle's law | temperature |
the constant in Charles's Law | pressure |
the constant in Gay Lussac's Law | volume |
this is loss during beta decay | an electron |
this is loss during alpha decay | a Helium atom (2 P + 2 N) |
this can partially block gamma rays | lead or concrete |
this can block alpha particles | sheet of paper |
this can block beta particles | wood or aluminum |
says that gases can be compressed due to the empty space between particles | kinetic theory |
says that gases tend to move from areas of high concentration to low concentration | diffusion |
the anion for bases | hydroxide ( OH- ) |
the cation for acids | hydrogen ( H+ ) |
creating energy by combining lighter unstable nuclei into heavier nuclei | nuclear fusion |
a series of self sustaining chemical reactions | nuclear chain reaction |
