As a review for newton's laws, my teacher has assigned my class to do an egg drop test. does anyone have any tips on what to use? so far, my group has sponges, marshmallows, air in a bag. also for the parachute, would cellophane or plastic work better?

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.

Argon, neon, and xenon are examples of
