What happens to an egg placed in corn syrup?
When you put a naked egg in corn syrup, you are creating a situation where the egg membrane separates two solutions with different concentrations of water. The egg white is about 90% water; corn syrup is about 25% water. So water migrates from inside the egg to outside the egg, leaving the egg limp and flabby.
What happens when the light hits the glass?
When light hits a glass object, some of the light bounces (or reflects) off the glass. The rest of the light keeps going through the glass object, but the light is bent (or refracted) as it moves from the air to the glass. The index of refraction for the oil is very close to the index of refraction for glass.
Is corn syrup hypertonic?
The corn syrup is a hypertonic liquid, ie. very concentrated with not much water compared to the egg.
What happens to light when it passes through the water?
As the light enters the water, it is refracted. Since the light is passing from air (less dense) into water (more dense), it is bent towards the normal. The beam of light would appear to bend at the surface of the water.
Why does corn syrup shrink an egg?
Water moves through the membrane easily. Bigger molecules, like the sugar molecules in the corn syrup, do not pass through the membrane. Since the egg membrane is semi-permeable, water can move in but proteins cannot move out. If a naked egg is placed in the corn syrup the egg will shrink.
What effect does corn syrup concentration have on the movement of water?
Because it allows small molecules, such as water, to pass through but not larger molecules, such as those in corn syrup. more water is drawn up into the thistle tube with higher concentrations of corn syrup. the ability of a solution to change the volume of a cell through osmosis.
What happens to the light rays as it passes from air to diamond and then back to air again?
For example, light refracts more when it passes from air to diamond than it does when it passes from air to water. That’s because the speed of light is slower in diamond than it is in water.
Is the light corn syrup in the dialysis tubing hypertonic or hypotonic to the water?
The light corn syrup in the dialysis tubing is hypotonic to the water because it increased in mass over the amount of time.
Why does refraction occur when light moves from air to water or air to water?
When light travels from air into water, it slows down, causing it to change direction slightly. This change of direction is called refraction. When light enters a more dense substance (higher refractive index), it ‘bends’ more towards the normal line.
When a light ray passes from air to water in the glass it changes its?
Therefore, when a light ray traveling through air enters water or glass it slows down, refracts, and bends toward the normal line. The opposite effect happens when light speeds up as it moves from one material into another.
