Statement 1: on a hot day a straight road from a distance appears wet. This happens because of refraction.
Statement 2: on a hot day the air above the road in contact with the road is hotter and less dense therefore has less refractive index than the cool air above it. When light comes through denser medium to rarer medium(here cooler air to hotter air) it is internally reflected which makes the road appear wet and shiny.
Statement 1 and 2 are correct but statement 2 is not the reason of statement 1
