Carbon-14 is radioactive and has a half-life of 5 700 years. The number of radioactive carbon-14 atoms in a very old piece of wood is found
to have decreased from 1 000 000 to 125 000.
Determine the age of the piece of wood.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
