If light passes into a material where the speed of light is faster, it will bend away from the boundary between the two materials. This occurs because light travels more slowly in denser materials, and when it exits into a less dense medium (where it travels faster), it refracts away from the normal line at the boundary. This behavior is described by Snell's law.
Material will travel faster in a river flowing down a steep slope. As the water slows down, the material will also slow down.
true
yes, if the state of matter is heated or cooled, the distance between the molecules in that object are either spread out or pulled together; therefore, the sound waves will travel quicker through heated material, and slower through cooled material.
true
Molecules in any material whose temperature is above absolute zero are in constant motion. The hotter the material the faster they move. Forces between the molecules tend to bring them together, but their motion keeps them apart. You could think of a skating rink with people skating in every direction. If the skaters are moving very slowly, the space between them can be smaller than if they are skating really quickly, when they have to keep a bigger distance between themselves.
indirect the smaller the particle the faster it will go or the larger the particle the more time it takes
Normally the flow of water through a course grained material will be faster than through a fine grained material as the pore spaces between the grains tend to be larger.
Material will travel faster in a river flowing down a steep slope. As the water slows down, the material will also slow down.
There are too many 'materials' to list but generally, sound travels faster in solids than in liquids, and faster in liquids than in gases. In other words, the denser the material, the faster sound travels.
So the molecules move faster and there will be more spontaneous spreading of the material which means that diffusion occurs. So the molecules move faster and there will be more spontaneous spreading of the material which means that diffusion occurs.
Yes, as the particles of a material move faster, they possess higher kinetic energy, which translates to an increase in temperature. This increase in temperature is a result of the increased vibration and movement of the particles within the material.
cotton dries faster than nylon because of cotton is a material which absorb water faster than nylon that is why cotton dries faster than nylon
true
Paper burn generally faster; but this depends also on the physical form of the material, humidity etc.
Sound travels faster the closer the particles are. Denser material has faster sound.
Sound travels about 15 times faster in steel compared to air.
Cheetah is faster between them. It is the fastest animal
