If 120 grams of potassium iodide (KI) are added to 100 grams of water at 15oC, how much more must be added to saturate the solution?

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.

Mechanical energy is when the amount of kinetic and potential energies added together remains the same. conserved created lost

Photons with the highest energy have the longest period
