Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the control variable in this experiment? the ray box used as the source of light the direction along which the light moves angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box

What postulate of the kinetic molecular theory best explains why gases have high fluidity? because collisions between gas particles are elastic, there is no loss of energy as particles flow past each other. because gases consist of large numbers of tiny particles, they spread out and do not come in contact with each other. because the attractive forces between gas particles are negligible, gas particles can glide easily past one another. because the average kinetic energy of gas particles increases as temperature increases, gas particles behave more like a liquid. question 6 compare the compressibility of gases and liquids. support your answer by describing the arrangement of particles in gases and liquids.
