In general, sound travels faster through
solids than through gases
gases than through solids
empty space than through matter
gases than through liquids
how has light been described?
as only a particle
as neither a wave nor a particle
as both a wave and a particle
as only a wave
what is amplitude?
amplitude is the number of complete waves that pass a point in a second.
amplitude is the height of a wave.
amplitude is the distance between two crests or two troughs.
amplitude is the time it takes for one complete wave to pass a given point.

An object displaces 652 ml of water. the volume of the object is: 0.652 cm³ 6.52 cm³ 65.2 cm³ 652 cm³

Which statement best describes the liquid state of matter? a. it has definite shape but indefinite volume. b. it has definite shape and definite volume. c. it has indefinite shape and indefinite volume. d. it has indefinite shape but definite volume.

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
