How does a Geiger counter measure radiation levels? Radiation is absorbed by gas atoms, which undergo phosphorescence and emit a different radiation.
Radiation is absorbed by gas atoms, which undergo nuclear reactions and emit a different radiation.
O Radiation knocks neutrons out of gas atoms, which causes the gas atoms to become unstable.
O Radiation knocks electrons out of gas atoms, which allows the gas to conduct an electric current.
the

most sediment washes or falls into the river as a result of mass movement and runoff. other sediment eroded from the bottom or sides of the river.

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
